Difference between Flutter and Angular

Flutter: Flutter is Google’s Mobile SDK to build native iOS and Android, Desktop (Windows, Linux, macOS), Web apps from a single codebase. It is an open-source framework created in May 2017. When building applications with Flutter everything towards Widgets – the blocks with which the flutter apps are built. They are structural elements that ship with a bunch of material design-specific functionalities and new widgets can be composed out of existing ones too. The process of composing widgets together is called composition. The User Interface of the app is composed of many simple widgets, each of them handling one particular job. 

The Software Development Kit contains a number of tools that will help you work on your applications. Some of these tools enable you to compile your code into native machine code on both iOS and Android. It comprises of UI Library based on widgets ie., It consists of reusable user interface elements (buttons, text fields, sliders, etc.) that can be refactored or modified as per your requirements.

The programming language that is used to develop Flutter apps is Dart. Dart is a typed object programming language that is created by Google in October 2011 but has improved a lot in the past few years. It is used for developing mobile as well as web applications. The main focus of Dart is for front-end development.

Advantageous features of Flutter:

  • Flutter uses a single codebase, called, Dart for both platforms, Android and iOS which is a simple language ensuring type safety.
  • Flutter is not bound to the ROM w.r.t. the widget system. So, it enhances its portability over a wide ambit of Android versions and thus, lowering its dependencies on the host platform.
  • Both Flutter language and community are developing with great speed, releasing new features, widgets and add-ons.
  • Dart and Flutter unite closely to optimize dart Virtual Machine(VM) for those mobiles which are specifically needed by Flutter.

 



Let’s understand the concept through an example.

Example: 

Dart




import 'package:flutter/material.dart';
  
void main() {
    runApp(GeeksForGeeks());
}
  
class GeeksForGeeks extends StatelessWidget {
  
    Widget build(BuildContext context) {
  
        // Material App
        return MaterialApp(
  
            // Scaffold Widget
            home: Scaffold(
                appBar: AppBar(
  
                    // AppBar takes a Text Widget
                    // in it's title parameter
                    title: Text('GeeksforGeeks'),
                ),
                body: Center(child: Text(
                'A Computer Science portal for geeks')),
            )
        );
    }
}

Output:

Angular: Angular is an open-source front-end framework that is mainly used to develop single-page web applications(SPAs). It is a JavaScript framework that is written in TypeScript. As a framework, It provides developers with a standard structure that enables them to create large applications in an easily maintainable manner. It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML.

The name “Angular” simply refers to the various versions of the framework. Angular was developed in the year 2009.



Key features of Angular:

Model View Controller(MVC): An architecture is basically a software pattern used to develop an application. It consists of three components in general, they are:  

  • Model: Used to manage the application data.
  • View: Responsible for displaying the application data.
  • Controller: The main job is to connect the model and the view component.

Normally when we talk about MVC architecture, we have to split our applications into these three components and then write the code to connect them. However, in AngularJs all we have to do is split the application into MVC and it does the rest by itself. It saves a lot of time and allows you to finish the job with less code. 

Data Model Binding: Data Binding in AngularJS is a two-way process, i.e. the view layer of the MVC architecture is an exact copy of the model layer. You don’t need to write special code to bind data to the HTML controls. Normally in other MVC architectures, we have to continuously update the view layer and the model layer to remain in sync with one another. In AngularJs it can be said that the model layer and the view layer remain synchronized with each other. Like when the data in the model changes, then the view layer reflects the change and vice versa. It happens immediately and automatically which helps in making sure that the model and the view is updated at all times. 

Some other features are:

  • Custom Components
  • Dependency Injection
  • Browser Compatibility

We will understand the concept through an example.

Example:

HTML




<html>
  <head>
    <title>AngularJS ng-app Directive</title>
  
    <script src=
    </script>
  </head>
  
  <body style="text-align: center">
    <h2 style="color: green">ng-app directive</h2>
  
    <div ng-app="" ng-init="name='GeeksforGeeks'">
      <p>{{ name }} is the portal for geeks.</p>
  
    </div>
  </body>
</html>

Output:

ng-app



Difference between Flutter and Angular:

S.No.

Flutter

Angular 

1.

Flutter is a Google UI toolkit for crafting beautiful, natively compiled applications for desktop, web and mobile from a single codebase.

Angular is a framework that is most suited to your application development. It is fully extensible and works well with other libraries.

2.

It is written in Dart languages.

It is written and developed in Windows Typescript language

3.

Flutter supports only mobile OS.

Angular supports both mobile and computer OS.

4.

Offers faster apps.

Offers comparatively slower.

5.

Comparatively lesser stability.



Offers a lot more stability.

6.

It does not support the 32-bit version of any app in iOS.

It supports the 32-bit version.

7.

Flutter works as SDK.

Angular works as a building block of the user interface.

8.

It uses components like Flutter Engine, Foundation library and Dart platform.

It uses components like Type Components, Data Binding and Dependency Injection.

9.

In flutter, operating systems design specific widgets to construct the applications.

In angular, service components are used to build the applications.

10.

Companies using flutter are Alibaba, Hamilton Musical, Abbey Road Studios app, Reflecting etc.

Companies using angular are Microsoft Office, Upwork, General Motors, YouTube, HBO etc.
