Flutter Background messages internationalization

Question

In my flutter app, i want to translate some text in the push notification body.

For foreground notifications. there is no problem.

For backgroud notifiactions i use :

void main() {
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
  runApp(MyApp());
}

And _firebaseMessagingBackgroundHandler must be a top-level function.

So, how can i use my famous AppLocalizations.of(context).cancel, since I don't have a context here ?

Answer 1

In MyApp create variable static Exp:

static BuildContext? mContext;

in build function of MyApp

mContext = context;

Answer 2

Since _firebaseMessagingBackgroundHandler is a top-level function- you can pass context as an optional parameter. So that you can access the context.

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message,
    {BuildContext? context}){
   
       //Your code
}
