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

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.
