App Development 101: Know more about Flutter

Flutter was introduced to the world by Google in 2017. It’s an open-source mobile development tool for creating high-quality mobile applications on iOS and Android. The applications are mainly written in Dart language. It is compatible with other programming languages like Java for Android and Objective C or Swift for iOS.

This article is a basic guideline for beginners to get friendly with the experience however, it requires a lot of in-depth knowledge to create specific applications on certain platforms.  

How to use Flutter

To start with Flutter, it is essential to know about the basic languages associated with it.

Next thing is to Install the Flutter SDK and any text editor. Flutter works great with Android studio but any other editor can be preferred too.

If any other physical device like iOS simulator is used then it will require installing XCode tools.

If Android Studio is used, consider the following steps to install Dart plugins.

  • First, select ‘Preferences’  from the toolbar.
  • Then, select ‘Plugins’ from the menu.
  • Then, click on the ‘Browse repositories’ button.
  • Now, search for Flutter and when the plugin appears to click on the ‘Install’ button.
  • Finally, click ‘Yes’ to install Dart plugins.
  • Restart Android Studio.

Creating an Application on Flutter

Assuming that all the required Flutter plugins are installed. At this point, the developer is ready to create a new Flutter application by tapping on the New project button and running the application demo.

  • First of all, replace the contents of lib/main.dart. with the following code ‘Hello World’ and delete all of the code from lib/main.dart.
  • Now, run the app by selecting the green arrow button in the IDE.
  • Install various packages or implement stateful widgets by using the Dart language.
  • Don’t forget to try the hot reload option for the better development cycle.

Programming with Dart

Dart is an easy and modern language as compared to other languages. To avoid any interruption between the process, it’s necessary to read the manual of specific guidelines involved with Dart language to enjoy the flutter experience.

Stateful Widgets

A Stateful Widget is a mutable data which changes in response to user interaction. It could be inserted by calling createState into the widget tree.

There’s a difference between a stateful widget and state. A widget is temporarily based on the presentation of the application while a State is more concrete in terms of remembering information

Creating an Interactive User face

An interactive user face generates an entire look of the application. It involves choosing different widgets, layouts, and animations according to user requirements.

The advanced UI system of Flutter incorporates certain gestures and motion effects to improve the user experience. Also, a navigator in Flutter enables the user to move freely from one route to another.

Firebase for Flutter

Firebase is a Back-end as a Service (BaaS) which serves as a background performer like managing the cloud storage or authenticating or hosting static files. It supports Flutter by creating a Firebase project first and then configuring it with Android or iOS applications.

The user can also add Flutter Fire plugins with specific codes to access APIs and services on each platform. Since flutter is cross-platform, the plugins are easily applicable to both the platforms.

Wrapping up

Since the scope of Flutter in increasing in the mobile development market, it is nearly impossible for developers to learn the basics of this tool without incorporating the Dart language.
