Make flutter application fullscreen

Question

How can I make a flutter application fullscreen. I already found out how to hide the status bar Hide Android Status Bar On Flutter App. but I can\'t seem to find how to hide

Answer 1

// to hide only bottom bar:
SystemChrome.setEnabledSystemUIOverlays ([SystemUiOverlay.top]);

// to hide only status bar: 
SystemChrome.setEnabledSystemUIOverlays ([SystemUiOverlay.bottom]);

// to hide both:
SystemChrome.setEnabledSystemUIOverlays ([]);

Answer 2

It's exactly like for Android status bar.

Doing SystemChrome.setEnabledSystemUIOverlays([]) hides both the status bar and the navigation bar.

p/s : use this SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values); to disable full screen mode.

Below code is working perfect for fullscreen

SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values);

import 'package:flutter/services.dart'; 
////

@override
Widget build(BuildContext context) {
///Set color status bar
 SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values);
   return Scaffold(
   backgroundColor: Colors.white,
   body: Center(
    child: Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: <Widget>[
        Image.asset(
          'images/ic_splash_logo.png',
          width: 97.0,
          height: 115.0,
          fit: BoxFit.contain,
        ),
        SizedBox(
          height: 10.0,
        ),
        Text(
          'iComplain',
          style: TextStyle(fontSize: 24,
              color: Color(0xFF174D73),
            fontFamily: 'Helvetica'
          ),
        ),
      ],
     ),
    ),
  );
}

Finally i found a way to set in one class for fullscreen. and disable on other classes.

To set full screen put this code in initState()

SystemChrome.setEnabledSystemUIOverlays([]);

and to set back to normal. In dispose()

SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values);

in the same class.

@override
  void dispose() {
        SystemChrome.setEnabledSystemUIOverlays(SystemUiOverlay.values);
    super.dispose();
  }
    
  @override
  initState() {
      SystemChrome.setEnabledSystemUIOverlays([]);
    super.initState();
  }

you can't set the

SystemChrome.restoreSystemUIOverlays();

in dispose(). because its already saying

**Restores the system overlays to the last settings provided via [setEnabledSystemUIOverlays].**
May be used when the platform force enables/disables UI elements.
          
For example, when the Android keyboard disables hidden status and navigation bars,
this can be called to re-disable the bars when the keyboard is closed.
          
On Android, the system UI cannot be changed until 1 second after the previous
change. This is to prevent malware from permanently hiding navigation buttons.`

Answer 5

this is my experience if i add SystemChrome.setEnabledSystemUIOverlays([]); in init or dispose , status bar and navigation bar will back when you use keyboard , but if you use it like this it work perfect:

  @override
  Widget build(BuildContext context) {

    // To make this screen full screen.
    // It will hide status bar and notch.
    SystemChrome.setEnabledSystemUIOverlays([]);

    // full screen image for splash screen.
    return Container(
            child: new Image.asset('assets/splash.png', fit: BoxFit.fill));
      }
    }

inside of your widget

The AppBar is your Navigation bar so just remove it from your Code as illustrate below

//New This Code it should work , the AppBar is navigation bar

import 'package:flutter/material.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {      
   @override
   Widget build(BuildContext context) {
      return new MaterialApp(
         home: new Scaffold(
           body: new Center(
              child: new Text('Hello World'),
           ),
         ),
      );
   }
}
