Unhandled Exception: Binding has not yet been initialized.

[a1573595]

• I have read the README
• I have done the setup for Android
• I have done the setup for iOS
• I have ran the sample app and it does not work there

Version

Technology	Version
Workmanager version	0.5.2
Xcode version	N/A
Swift version	N/A
iOS deployment target	N/A

Describe the error
The same problem(#431) appears again in version 0.5.2. You need to add WidgetsFlutterBinding.ensureInitialized() before Workmanager().initialize. If this is necessary, please update the example.

void main() {
  Workmanager().initialize(
      callbackDispatcher, // The top level function, aka callbackDispatcher
      isInDebugMode:
          true // If enabled it will post a notification whenever the task is running. Handy for debugging tasks
      );

  runApp(const MyApp());
}
