The pub.dev Firebase Messaging example located at the link below fails to compile in the Flutter/Android Studio with the following error:
Undefined class 'MessageArguments'.
The source code and libraries are here: [https://github.com/firebase/flutterfire/tree/master/packages/firebase_messaging/firebase_messaging/example][2]
Has anyone successfully compiled this example, and/or do you have suggestions how to resolve this error?
You can use this and it is from message.dart
/// Message route arguments.
class MessageArguments {
/// The RemoteMessage
final RemoteMessage message;
/// Whether this message caused the application to open.
final bool openedApplication;
// ignore: public_member_api_docs
MessageArguments(this.message, this.openedApplication);
}
Also It is better to accept null from route.
final MessageArguments? args = ModalRoute.of(context)?.settings.arguments;
Do a null check when using this args.
