Я пытаюсь получить токен для облачных сообщений Firebase в своем приложении. который работает на эмуляторе android Что здесь не так? Я пытался flutter run, но это не работает, я использовал 1.firebase_messaging: ^ 6.0.9 в качестве зависимости и 2.
import 'package:flutter/material.dart';
import 'package:firebase_messaging/firebase_messaging.dart';
class Notifications_ extends StatefulWidget {
@override
_Notifications_State createState() => _Notifications_State();
}
class _Notifications_State extends State<Notifications_> {
final FirebaseMessaging _messaging=FirebaseMessaging();
@override
void initState() {
super.initState();
_messaging.getToken().then((token)
{
print(token);
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('notification'),
),
body: Text('body testing'),
);
}
}
