Flutter = Google’s mobile UI Framework

So Flutter makes expressive and fast way to deliver the application. To built native apps on Android and iOS. Flutter makes it possible to produce the application and UI from the single codebase which is compiled directly to the native arm code. By using GPU and to access platform API’s.

What is Flutter?

Flutter is an app SDK from a single codebase. Apps are built using Dart language. It is a complete Framework with tools and widgets.

Flutter is super easy when you are familiar with Java, JS, and Kotlin, Swift or C #.

Flutter highlights:

  1. Open source and Free.
  2. Fast Development.
  3. Flutter integrates with popular development tools.
  4. Flutter has set of customizable widgets.
  5. Expressive and Flexible User Interface.
  6. Complete control on every pixel of the application.
  7. Achieved through merging gestures, widgets, rendering and animation in the Flutter.
  8. Flutter follows platform conventions and interface details.
  9. Such as navigations, icons and fonts.
  10. Flutter apps are found on both App Store and Google Play Store.
  11. Fast, Fun at the same time modern ways to deliver the native applications.

Core Principle of flutter:

For Flutter everything is a widget. It is the building block of the flutter app. Unlike other frameworks Flutter has a consistent and unified object model called widget. Widget is formed with number of small widgets which serve single purpose.

Flutter framework:

Flutter is a series of layers which is build on previous layer. The upper layers are used frequently than the lower layers. Through these layers you will be getting lot of mix and match options. So you can unleash your whole creative power to describe and produce your application.

How to install Flutter framework?

  1. Initially navigate to flutter official website – flutter.dev
  2. In the homepage, you can choose your operating system.
  3. Next page shows the system requirements like

For windows

  • Operating System windows 7 or later.
  • The system should contain more than 400 MB disk space.
  • Git for Windows 2.x and Windows PowerShell 5.0.
  • Next download and install the Flutter SDK.
  • Then update the path in the windows console.
  • After that run flutter doctor.
  • Now you can continue with android setup.
  • Install Android Studio and setup your android device and emulator.

For macOS

  • Operating System 64 bit.
  • The system should contain more than 2.8 GB disk space.
  • Flutter depends on tools like Git 2.x, mkdir, curl, bash, zip, which, unzip and rm.
  • Now download flutter SDK and extract it in the desired location.
  • Then Run flutter doctor.
  • After that update your path and setup your platform.
  • Now install Xcode and setup iOS simulator.
  • Further start to create and run a Flutter app.
  • Now deploy to iOS device then continue with android setup.
  • Install Android Studio and setup your android device and emulator.

For Linux:

  • Operating System 64 bit.
  • The system should contain more than 600 MB disk space.
  • Flutter depends on tools like xz-utils, Git 2.x, mkdir, curl, bash, zip, which, unzip and rm.
  • Now download flutter SDK and extract it in the desired location.
  • Then Run flutter doctor and update your path and setup your platform.
  • After install Android Studio then setup your Android Device.
  • Now setup the Android Emulator.

How to set up an editor for Flutter?

  1. You can install Android Studio or IntelliJ IDEA Community and IntelliJ IDEA Ultimate. Then install flutter and Dart plugins.
  2. If not you can install VS Code. Then install Flutter and Dart plugins.
  3. Next validate your setup with Flutter Doctor.

Difference between Android Studio and Flutter:

Android Studio is based on IntelliJ IDEA Flutter is a mobile app SDK for both iOS and Android.
Android is getting better day by day Flutter is HOT reload
It is Google’s official android IDE Backed by Google
Powerful and robust Flutter is cross platform
Intelligent code editor Compiled into native code.
It has slow emulator It lacks friendly documentation
Android Studio slow release process It has no 3D Graphics Engine support
Contains great layout design Compiled into native code.

 

Tools integrated with flutter:

Firebase, Android SDK, Socket I.O, Dart, Taboola, Outbrain, Razorpay, Fish Redux, Google AdMob, Appwrite and CanvasjS.

 Advantages of flutter:

  • Less code writing – Hot Reload.
  • Suitable for Minimum Viable Product (MVP)
  • No additional cost for supporting older OS.
  • Single code for two codebases (Android, iOS).
  • Flutter supports Android jelly bean or newer.
  • In iOS it supports version 8 or newer.
  • Easy to create own widgets and customizable applications.
  • Smooth and fast app working.
  • If your app is for two codebase you can write the automatic testing code only once. So it saves the testing time.

Disadvantages of flutter:

  1. Flutter doesn’t support Travis and Jenkins.
  2. Can’t be compared to the native development in case of libraries and support.
  3. Flutter team is actively improving.
  4. Debugging is not up to the mark.
  5. Error screens and log are not clear and obscure.

Flutter doesn’t allow you to build clean and maintainable architecture.
