What Makes Flutter the Best Cross-Platform for Mobile App Development ?

Mobile app development is rapidly evolving, tech companies around the world are releasing disruptive cross-platform technologies making it easier and efficient to craft stunning mobile apps.

Flutter app development is one such cross-platform technology that has taken the industry by storm.

Flutter, created by Google, is an open-source UI software development toolkit that allows developers to create native apps for mobile, web, and desktop from a single codebase.

This means that with Flutter, developers can build stunning and high-performance apps for iOS, Android, and more, using a single codebase. This ability greatly streamlines the development process and enhances consistency across platforms.

An Introduction to the Widget-Based Flutter Architecture

  1. Widget-Based Architecture:

At the heart of Flutter development architecture is its widget-based approach. In Flutter, everything is a widget – from the smallest UI elements like buttons and text to entire complex layouts.

This includes both the visual components that users see and the structural components that define the app’s behaviour.

This concept of encapsulating different parts of an app’s UI and functionality as widgets enables Flutter app developers to simplify the development process and promotes code reusability.

  • Stateless Widgets:

Stateless widgets are immutable, meaning they don’t change over time or in response to user interactions.

They represent the static elements of an app’s user interface, like icons, text labels, and images.

Since these widgets do not have internal state, they can be thought of as pure functions that take input and return UI elements based on that input.

  • Stateful Widgets:

Stateful widgets, on the other hand, are mutable and can change their appearance or behaviour over time.

These widgets are used to manage dynamic user interactions, such as updating the display when a user taps a button or enters data into a text field.

Stateful widgets maintain a “state” object that can be updated, triggering the widget tree to rebuild and reflect the changes.

  1. Widget Tree and Element Tree:

The widget-based architecture forms a hierarchical structure known as the “Widget Tree.”

The Widget Tree represents the arrangement of widgets within the app’s user interface. It defines how widgets are nested within each other and establishes the visual hierarchy of the app.

When the app is run, it takes the Widget Tree and converts it into an “Element Tree.” Elements are an optimized representation of widgets and form the basis for rendering.

Flutter’s rendering engine then uses the Element Tree to efficiently paint the UI on the screen.

  1. Reconciliation and “Hot Reload”:

One of the standout features of Flutter’s architecture is its reconciliation process.

When changes are made to the Widget Tree – for example, when a user interacts with an element – it efficiently calculates the difference between the previous and updated trees.

This process is known as “reconciliation” or “diffing,” and it ensures that only the necessary parts of the UI are updated, optimizing performance.

Moreover, it’s “Hot Reload” feature is closely tied to its architecture.

Hot Reload allows Flutter app developers to make changes to the code and instantly see the results in the app without restarting it.

This rapid iteration cycle enhances productivity and expedites the development process.

  1. Platform Channels and Native Integration:

While the platform aims to provide a consistent experience across platforms, it also acknowledges the need for platform-specific features and capabilities. To achieve this, Flutter incorporates “platform channels.”

These channels allow the code to communicate with native code written in languages like Java (for Android) and Swift (for iOS).

This way, developers can access native device functionalities and seamlessly integrate platform-specific features while still maintaining the majority of the codebase.

Android Architecture Patterns and Their Differences

Android Architecture Patterns can help you create mobile apps with fewer bugs, better maintainability and testable code. These include Layered Architecture, Model-View-Controller, Data-Table-Fragment, Single-Page Applications, and Microscope. They focus on different areas of an app, from how to structure your app to how you should handle user interactions with it.

What is Architecture?

If you are building an application in an organized manner with some set of rules, describe proper functionalities and implement it with proper protocols, then it is called an Architecture.

Role of Architecture

Let us say if we are not using any architecture and we are writing our code in a class/activity/ fragment in an unorganized manner then the problems we will face are-

  • The number of lines of code will increase that it will become complex to understand.
  • It decreases readability and increases the number of bugs. Thus, it is difficult to test and reduces the quality of the product.

So, to provide clear data flow which will increase robustness, scalability, bug resistant, increase readability, easy to modify and increase productivity and provide a quality app. Thus, we should use proper architecture, suitable to work in a team.

But why does your app need good architecture?

A simple answer is that everything should be organized in a proper way. So does your Android project. If not, the following problems sound familiar to you: All of your codes are not covered by Unit Tests.

  • It is difficult to debug a class because it contains a huge number of functions.
  • You are unable to keep track of the logic inside that huge class.
  • Another developer finds it so difficult to maintain and add new features to your work.

So, if you are going to build a high-quality app, you should care about architecture.

What does your app get from a proper architecture?

  • Simplicity: Separate and define a clear single role for each component in your app. A class is not going to be a multi-tasking component. You will find it easy to know what it does and what is inside it. It advocates the Keep It Stupid Simple (KISS).
  • Testability: Before we can apply Unit Tests, we have to write testable codes.
  • Low-cost maintenance: It is easy to add, and remove features. Especially, it helps us to keep track of important logic parts.

The When & How?

Several upcoming questions maybe appear in your head.

  1. So, what is the best architecture pattern for my Android apps?
  2. And how can I apply that pattern in the most effective way?
    • There is no single candidate that suits all of your Android projects because the design pattern is abstract and its implementation depends on specific requirements.
    • Fortunately, the more we understand about it, the more effectively and properly we apply them.
    • You can use different architectures across different apps. Even, in one complex project, each module has its own structure.

Another question?

So, if I have never used any architecture in my Android apps yet. So, what should I do?

Just pick up one of them. Read about it, try to apply it. After that, you will become familiar with it and have your own best practices.

Developers out there are talking about these following popular patterns:

  • MVC ( Model — View — Controller)
  • MVP ( Model — View — Presenter)
  • MVVM (Model — View — View Model)

Some principles for good Architecture in Android

To get good architecture there are some basic concepts we should follow. They are:-

  • Separation of concern: Component should do what it is required. Shown in the diagram.

Architecture Pattern

This we can achieve by Architecture pattern.

  • No Hard dependency: It should be fixed if every component should work on some limited amount of dependency. All dependencies should be provided from outside. Tips: Use Dependency Injections.
  • Manage lifecycle and data persistence: It can be achieved by Architecture Component.

MVC:

It is a Model-View-Controller. The most commonly used architecture. These are the three components used in MVC.

  • Model– It is business logic and Data State. Getting and manipulating the data, communicates with the controller, interacts with the database, sometimes update the views.
  • View– What we see. User Interface consists of HTML/CSS/XML. It communicates with the controller and sometimes interacts with the model. It passed some dynamic views through the controller.
  • Controller– It is Activity/Fragment. It communicates with view and model. It takes the user input from view/REST services. Process request Get data from the model and passes to the view.

Advantages

  • It keeps business logic separate in the model.
  • Support asynchronous techniques
  • The modification does not affect the entire model
  • Faster development process

Disadvantages

  • Due to large code controller is unmanageable.
  • Hinders the Unit testing
  • Increased Complexity

MVC

MVP:

It as Model-View-Presenter. For the phase of developing time or for the phase of developers it is vital to divide the architecture into layers. It breaks the dependency on what we have on view.

  • Model– It is business logic and Data State. Getting and manipulating the data, communicates with the presenter, interacts with the database. It doesn’t interact with the view.
  • View – Consists of UI, activity, and fragment. It interacts with the presenter.
  • Presenter– It presents the data from the model. Control all the behavior that want to display from the app. It drives the view. It tells view what to do. Any interaction between the model and the view is handled by the presenter. Saves the data back to the model.

Advantages

  • It makes view dumb so that you can swap the view easily.
  • Reusable of View and Presenter
  • Code is more readable and maintainable
  • Easy testing as business logic separated from UI

Disadvantages

  • Tight coupling between View and Presenter
  • Huge amount of interfaces for interaction between layers.
  • The code size is quite excessive.

MVP

MVVM:

It is a Model-View-View Model. It losses the tight coupling between each component and reduces the glue classes. Works on the concept of observables. Children don’t have reference to the parent, they only have reference by observables.

  • Model– It has business logic, local and remote data source and repository. Repository: communicate with local or remote data sources according to the request from View Model.
  • View– Only user interaction i.e.XML, no business logic. Direct send user action to view model but does not directly get a response. To get a response view observes some data which View Model exposes.
  • View Model– Most of the user interface logic center it here. It is a bridge between a view and a business logic. It does not have any clue which view has to use it. As it does not have a direct reference to the view. Thus, good in testing and has loose coupling. But still, it needs to update the UI this interaction done by observables. When data changes observable notifies.

Advantages

  • No tight coupling between the view and view model
  • No interfaces between view and model.
  • Easy to unit testing and code is event-driven.

Disadvantages

  • You have to create observables for each UI component.
  • The code size is quite excessive.

MVVM

Difference between MVC, MVP & MVVM Design patterns

MVC (Model View Controller)

  • One of the oldest software architecture
  • UI (View) and data-access mechanism (Model) are tightly coupled.
  • Controller and View exist with the one-to-many relationship. One Controller can select a different View based upon required operation.
  • The View has no knowledge about the Controller.
  • Difficult to make changes and modify the app features as the code layers are tightly coupled.
  • User Inputs are handled by the Controller.
  • Ideal for small scale projects only.
  • Limited support to Unit testing.
  • This architecture has a high dependency on Android APIs.
  • It does not follow the modular and single responsibility principle.

MVP (Model View Presenter)

  • Developed as the second iteration of software architecture which is advance from MVC.
  • It resolves the problem of having a dependent View by using Presenter as a communication channel between Model and View.
  • The one-to-one relationship exists between Presenter and View as one Presenter class manages one View at a time.
  • The View has references to the Presenter.
  • Code layers are loosely coupled and thus it is easy to carry out modifications/changes in the application code.
  • The View is the entry point to the Application
  • Ideal for simple and complex applications.
  • Easy to carry out Unit testing but a tight bond of View and Presenter can make it slightly difficult.
  • It has a low dependency on the Android APIs.
  • Follows modular and single responsibility principle

MVVM (Model View View Model)

  • Industry-recognized architecture pattern for applications.
  • This architecture pattern is more event-driven as it uses data binding and thus makes easy separation of core business logic from the View.
  • Multiple View can be mapped with a single View Model and thus, the one-to-many relationship exists between View and View Model.
  • The View has references to the View Model
  • Easy to make changes in the application. However, if data binding logic is too complex, it will be a little harder to debug the application.
  • The View takes the input from the user and acts as the entry point of the application.
  • Not ideal for small scale projects.
  • Unit testability is highest in this architecture.
  • Has low or no dependency on the Android APIs.
  • Follows modular and single responsibility principle.

Conclusion

When it comes to Android, both MVP and MVVM offer better modular architecture than MVC. Though, they also tend to add more complexity to your app.

In simpler applications which involves two or more screens, MVC can work fine in Android. Whereas in more complex cases where your application needs to be developed considering to add more features in future, MVVM with data binding will make you write lesser code.

Android architecture describes how a mobile app should be structured internally. By understanding the pros and cons of different patterns, you can make your app more maintainable and scalable.

Although the app market is still in its infancy, the number of successful mobile apps is growing exponentially. It’s no surprise then that the number of new mobile app development patterns are emerging at an equally rapid rate.

So, which architectural design pattern are you going to consider for your mobile application?

Key Difference Between ReactJS And React Native

ReactJS and React Native are two leading JavaScript frameworks that allow users to build mobile user interfaces (MUI). They both provide developers with an opportunity to quickly prototype mobile apps and manage complexity as projects grow in scope. Both ReactJS and React Native are used to create native-like apps. However, there are certain differences between the two. Let me explain one by one

What is ReactJS?

React.JS often referred to as React or ReactJS is a JavaScript library responsible for building a hierarchy of UI components or in other words, responsible for the rendering of UI components. It provides support for both front-end and server-side.

Advantages of ReactJS

  1. Easy to learn and use: ReactJS is much easier to learn and use. Any developer who comes from a JavaScript background can easily understand and start creating web apps using react.
  2. Creating dynamic web applications becomes easier: To create a dynamic web application specifically with HTML was tricky, which requires complex coding, but ReactJS solved that issue and makes it easier. It provides less coding and gives more functionality.
  3. Reusable components: ReactJS web application is made up of multiple components, and each component has its logic and controls. These components can be reused wherever needed. The reusable code helps to make your apps easier to develop and maintain.
  4. Performance enhancement: ReactJS improves performance due to virtual DOM. The React Virtual DOM exists entirely in memory and is a representation of the web browser’s DOM. Due to this, when we write a react component, we do not write directly to the DOM. Instead, we are writing virtual components that will turn into the DOM, leading to smoother and faster performance.
  5. The support of handy tools: ReactJS supports a handy set of tools which make the task of the developers understandable and easier.

What is React Native?

React Native is an open-source JavaScript framework used for developing a mobile application for iOS, Android, and Windows. It uses only JavaScript to build a cross-platform mobile app. React Native is the same as react, but it uses native components instead of using web components as building blocks. It targets mobile platforms rather than the browser.

Facebook developed the React Native in 2013 for its internal project Hackathon. In March 2015, Facebook announced that React Native is open and available on GitHub.

Advantages of React Native

There are several advantages of React Native for building mobile applications. Some of them are given below:

  1. Cross-Platform Usage: It provides the facility of “Learn once write everywhere.” It works for both platform Android as well as iOS devices.
  2. Class Performance: The code written in React Native is compiled into native code, which enables it for both operating systems as well as it functions in the same way on both the platforms.
  3. JavaScript: JavaScript knowledge is used to build native mobile apps.
  4. Community: The large community of ReactJS and React Native helps us to find any answer we require.
  5. Hot Reloading: Making a few changes in the code of your app will be immediately visible during development. If the business logic is changed, its reflection is live reloaded on screen.
  6. Improving with Time: Some features of iOS and Android are still not supported, and the community is always inventing the best practices.
  7. Native Components: We will need to write some platform specific code if we want to create native functionality, which is not designed yet.
  8. Existence is Uncertain: As Facebook develops this framework, its presence is uncertain since it keeps all the rights to kill off the project anytime. As the popularity of React Native rises, it is unlikely to happen.

Disadvantages of React Native

  1. React Native is still new and immature: React Native is a newbie in Android and iOS programming languages and is still in its improvement stage, which can have a negative impact on the apps.
  2. Learning is tough: React Native is not easy to learn, especially for a fresher in the app development field.
  3. Lacks the Security Robustness: React Native is a JavaScript library and open-source framework, which creates a gap in the security robustness. When you are creating banking and financial apps where data is highly confidential, experts advise not to choose React Native.
  4. Takes More Time to Initialize: React Native takes a lot of time for initializing the runtime even for the hi-tech gadgets and devices.

ReactJS vs React Native

ReactJS

React Native

ReactJS initial release was in 2013. React Native initial release was in 2015.
Used for developing web applications. Used for developing mobile applications.
Can be executed on all platforms. Not platform independent. It takes more effort to be executed on all platforms.
Uses React-router for navigating web pages. Built-in navigator library for navigating mobile applications.
Uses HTML tags. Does not use HTML tags.
Use code components, which saves a lot of valuable time. Reuse React Native UI components and modules which allow hybrid apps to render natively.
Provides high security. Provides low security in comparison to ReactJS.
The Virtual DOM renders the browser code. Native uses its API to render code for mobile applications.

Which is better, React or React native?

Both ReactJS and React Native are important pillars for app and web development, and due to their flexible functionalities and an evolving Eco-system of libraries, they are gaining momentum with each passing day.

While ReactJS is basically a JavaScript library and React Native is the entire framework, the former is the heart of the latter, and compliments each other.

If ReactJS is optimal for creating apps with high functionality and complex calculations, then React Native is ideal to give a native feeling to your mobile apps.

Conclusion

React is a framework for building applications using JavaScript. React Native is an entire platform allowing you to build native, cross-platform mobile apps, and React.JS is a JavaScript library you use for constructing a high performing UI layer.

React.JS is the heart of React Native, and it embodies all react principles and syntax, so the learning curve is easy. The platform is what gave rise to their technical differences. Like the browser code in React is rendered through Virtual DOM while React Native uses Native API’s to render components on mobile.

So both the framework has huge market demand for web and mobile application development. We have also expertise in developing application in react and react native. If you have any quarries on these two framework then please book a free consultation or if you are looking to develop application on these two framework then you are in the right place.

An Introduction To BuildContext In Flutter and It’s Importance?

BuildContext is the object that stores information about the current build. It provides information such as the minimum and maximum supported Flutter version, the device’s screen size and pixel density, the currently active theme, and more.

The BuildContext is the set of inputs that Flutter uses to create an instance of a widget. It includes properties on the Android and iOS platforms, as well as properties related to the current device and environment.

It can be used to customize the behavior and appearance of your widget, but it’s important to understand how it works in order to avoid any issues.

For instance, you can use BuildContext.host () to get a string that specifies the current app’s host name. You can also use BuildContext.local (context).emulator so you can set up an emulator for testing your app on different devices without needing to change settings in Android Studio every time you want to switch emulators.

Flutter is one of the hottest technologies for cross-platform mobile development. It has been described as a new contender in the app development industry, competing with traditional frameworks like React Native and Xamarin.

Flutter builds on Google’s own Dart programming language and provides a library of scalable, customizable UI widgets to help developers build beautiful native interfaces that run across all platforms. It has been designed to help developers build high-quality, natively compiled apps that run on both Android and iOS from one codebase.

What is a BuildContext?

The BuildContext is a locator that is used to point the location of the widget in the widget tree.

In Flutter we have to create widgets through the build method & we have to pass the BuildContext as an argument to the build method.

Each BuildContext is different for every widget. Each widget you create has its own BuildContext and they can locate themselves in the widget tree or reach out to the nearest widget.

This is how we create a widget

[code language=”css”]
Widget build (BuildContext context)=> MyAwesomeWidget();
[/code]

Flutter widget tree

Everything in Flutter is a widget. Whether it is a container, providers, text, button, image etc. everything is a widget, whether it reflects the UI in the app or not.

The UI or display in Flutter comprises stacks of widgets popularly called a widget tree. Each component is responsible for a small unit of the entire UI.

Flutter widget tree

The above image is an example of a widget tree in Flutter. We can observe that every widget has its own place in the widget tree i.e. the Button widget is under column widget.

Widgets are only visible to its BuildContext or to its parent’s BuildContext. That means we can locate the parent widget from the child widget. For the above image tree structure we can get Scaffold from Container by going up:

[code language=”css”]
context.ancestorWidgetOfExactType(Scaffold)
[/code]

You can also locate a child widget from a parent widget and for that, we use Inherited Widgets.

There are three main trees in Flutter:

  1. Widget
  2. Element
  3. Render

Widget

Widgets are immutable, they represent the structure for RenderObjects Fluorescence is optimized, which can easily create and destroy widgets without any significant performance implications.

The same can’t be said for RenderObjects.

Element

In the middle of Widgets and RenderObjects sits elements. These act as the glue between the immutable widget layer and the mutable render layer.

As the configuration of a widget changes (for example, the user calls the set state that triggers a rebuild), the element notices incoming changes and says to the corresponding render object,

“Hey! Please update. ”

Render

RenderObjects are what the visual pieces on the screen correspond to. Their purpose is to define areas on the screen regarding their spatial dimensions. They are referenced by the element. As a consequence we are dealing with another (third) tree here: the RenderObjects together form a tree which is called Render Tree whose root node is a RenderView (being a variant of a RenderObject). The RenderObject, on the other hand, are mutable objects that do the heavy lifting of turning the configuration supplied from widgets into pixels users can see and interact with on the screen.

Unlike widgets that are cheap and can safely be created and destroyed without any significant performance implications, the same cannot be said for RenderObjects.

For this reason, whenever the configuration of a widget changes, the framework looks at the change and updates the associated RenderObject instead of creating a new one each time.

Conclusion

Understanding BuildContext is very crucial to develop applications in Flutter. This improves our knowledge on how Flutter works and helps to build apps confidently.

BuildContext is a facade that provides a consistent API for implementing custom layouts and animations. The code is platform-specific, but the abstraction weaves some of the underlying platform-specific logic out of sight. BuildContext also helps reduce the need to know about the underlying platform details when implementing custom layouts and animations.

I’ve worked with the team at Andolasoft on multiple websites. They are professional, responsive, & easy to work with. I’ve had great experiences & would recommend their services to anyone.

Flutter is an open-source mobile app SDK that is used to make a high-quality app with a beautiful and consistent user experience. Unlike native mobile development, Flutter does not require that an app has a single, complete codebase but instead lets you mix and match code for different platforms. It also provides a rich set of pre-built widgets and allows for shared state.

The BuildContext is the context in which the Flutter app is running and is used for determining where to find resources and strings. It can be thought of as the environment in which the app is being used. Flutter provides an abstract class called BuildContext that handles the loading of resources, without requiring the developer to use hardcoded paths. This abstraction is one of the things that makes flutter so easy to use.

Flutter provides a set of high-level classes to help flutter developers build reactive user interfaces. Are you looking to develop an application in flutter framework? Let’s discuss
