How to Enable or Disable Full Screen Mode in Flutter App
Introduction
Flutter is an open-source mobile app development framework created by Google. It is used to develop natively compiled applications for mobile, web, and desktop from a single codebase. One of the key features of Flutter is its ability to enable or disable full-screen mode. In this blog post, we will discuss how to enable or disable full-screen mode in a Flutter app.
Enabling Full Screen Mode
To enable full-screen mode in a Flutter app, you can use the `SystemChrome` class. This class provides a way to control the system chrome, including the ability to enable or disable full-screen mode. Here is an example of how to enable full-screen mode:
“`dart
import ‘package:flutter/services.dart’;
void enableFullScreenMode() {
SystemChrome.setEnabledSystemUIOverlays([]);
}
“`
Disabling Full Screen Mode
To disable full-screen mode in a Flutter app, you can use the `SystemChrome` class again. This time, you need to pass a list of system UI overlays that you want to enable. Here is an example of how to disable full-screen mode:
“`dart
import ‘package:flutter/services.dart’;
void disableFullScreenMode() {
SystemChrome.setEnabledSystemUIOverlays(
[SystemUiOverlay.top, SystemUiOverlay.bottom],
);
}
“`
Using Full Screen Mode in a Flutter App
To use full-screen mode in a Flutter app, you can call the `enableFullScreenMode` or `disableFullScreenMode` function at the appropriate time. For example, you can call the `enableFullScreenMode` function when the app starts, and the `disableFullScreenMode` function when the app is paused. Here is an example:
“`dart
import ‘package:flutter/material.dart’;
import ‘package:flutter/services.dart’;
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
enableFullScreenMode();
return MaterialApp(
title: ‘Full Screen Mode’,
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
MyHomePageState createState() => MyHomePageState();
}
class _MyHomePageState extends State
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
child: Text(‘Disable Full Screen Mode’),
onPressed: () {
disableFullScreenMode();
},
),
),
);
}
}
“`
Conclusion
In conclusion, enabling or disabling full-screen mode in a Flutter app is a straightforward process. You can use the `SystemChrome` class to control the system chrome and enable or disable full-screen mode. By following the examples in this blog post, you can easily enable or disable full-screen mode in your Flutter app.
