import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(); // 初始化Firestore

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Firestore Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final CollectionReference collection =
      FirebaseFirestore.instance.collection('dataCollection');

  final List<String> data = ['item1', 'item2', 'item3']; // 定义要添加的数据

  void addDataToFirestore() {
    collection.doc('documentId').set({'fieldName': data}); // 将数据添加到Firestore中
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Firestore Demo'),
      ),
      body: Center(
        child: RaisedButton(
          onPressed: addDataToFirestore,
          child: Text('Add Data to Firestore'),
        ),
