 Alteratively, you can the `SystemThemeBuilder` widget to listen to changes on the system accent color:
 
 ```dart
-SystemThemeBuilder(builder: (context, accent) {

-### Checking if accent color is supported

-The `flutter/foundation` package provides a `defaultTargetPlatform` getter, which can be used to check what platform the current app is running on.

-You can check if the current platform supports accent colors using this extension method:
-
-```dart
-import 'package:flutter/foundation.dart' show defaultTargetPlatform;
-
-void main() {
-  final supported = defaultTargetPlatform.supportsAccentColor;
-
-  print('Accent color is: ${supported ? 'supported' : 'not supported'} on the current platform');
