Flutter - How to set status bar color when AppBar not present

How to set status bar color when AppBar not present.

I have tried this but not working.

Widget build(BuildContext context) {
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);
    return new Scaffold(
        body: new Container(
        color: UniQueryColors.colorBackground,
        child: new ListView.builder(
           itemCount: 7,
           itemBuilder: (BuildContext context, int index){
             if (index == 0){
               return addTopInfoSection();
             }
           },
        ),
       ),
    );
}

Output look like this:

First, import services package:

import 'package:flutter/services.dart';

Next, simply put this in the build function of your App:

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
  statusBarColor: Colors.blue, //or set color with: Color(0xFF0000FF)
));

Additionally, you can set useful properties like: statusBarIconBrightness, systemNavigationBarColor or systemNavigationBarDividerColor

If you prefer a more flutter/widget way of doing the same thing, consider using the AnnotatedRegion<SystemUiOverlayStyle> widget.

The value: property can be set to a SystemUiOverlayStyle() object containing the same properties as shown above.

If you take a look at the source code of AppBar, you can see they use an AnnotatedRegion widget. AnnotedRegion widget gives you more control on System overlay style. This is a more fluttery way to configure the system styles when an app bar is not used.

From my understanding, this widget automatically sets the statusbar/navigationbar color when the widget wrapped in it gets overlaid by the statusbar/navigationbar.

You can wrap your widget like this:

import 'package:flutter/services.dart';

...    

Widget build(BuildContext context) {
   return Scaffold(
      body: AnnotatedRegion<SystemUiOverlayStyle>(
         value: SystemUiOverlayStyle.light,                
         child: ...,
      ),
   );
}

For more information about AnnotatedRegion widget head over to the API Docs

As the solution is already mentioned, I am implementing it in a different approach. The approach followed is removing AppBar and changing the color of the status bar using Container widget.

void main() {
  runApp(
    MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Test',
      home: Scaffold(
        primary: true,
        appBar: EmptyAppBar(),
        body: MyScaffold(),
      ),
    ),
  );
}

class MyScaffold extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Text(
        'Test',
      ),
    );
  }
}

class EmptyAppBar extends StatelessWidget implements PreferredSizeWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.black,
    );
  }

  @override
  Size get preferredSize => Size(0.0, 0.0);
}

• Here I am using EmptyAppBar class for removing the AppBar which is by default present in Scaffold
• In EmptyAppBar class we can choose the required color in the container widget.
• After that, you have your own custom MyScaffold class for creating your widgets. In my code, I've created a text.

Reference: GitHub Issue

On Android, add the following to onCreate in MainActivity.java, after the call to super.onCreate(savedInstanceState);

getWindow().setStatusBarColor(0x00000000);

or you can use the the flutter_statusbarcolor plugin

   changeStatusColor(Color color) async {
    try {
      await FlutterStatusbarcolor.setStatusBarColor(color);
    } on PlatformException catch (e) {
      print(e);
    }
  }
