尝试使用Flutter将"Events“集合添加到我的Firebase Firestore

dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^1.0.0
  cloud_firestore: ^2.2.0

import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

import 'package:cloud_firestore/cloud_firestore.dart';

void addEventsCollection() {
  FirebaseFirestore firestore = FirebaseFirestore.instance;
  firestore.collection('events').add({
    'title': 'Event Title',
    'description': 'Event Description',
    'date': DateTime.now(),
  });
}

import 'package:cloud_firestore/cloud_firestore.dart';

void fetchEvents() {
  FirebaseFirestore firestore = FirebaseFirestore.instance;
  firestore.collection('events').get().then((QuerySnapshot querySnapshot) {
    querySnapshot.docs.forEach((DocumentSnapshot document) {
      print(document.data());
    });
  });
}
