将快照数据传递给Flutter Widget

class MyWidget extends StatelessWidget {
  final String snapshotData;

  MyWidget(this.snapshotData);

  @override
  Widget build(BuildContext context) {
    return Text(snapshotData);
  }
}

MyWidget('Snapshot Data');

class MyWidget extends StatelessWidget {
  final String snapshotData;

  MyWidget({required this.snapshotData});

  @override
  Widget build(BuildContext context) {
    return Text(snapshotData);
  }
}

MyWidget(snapshotData: 'Snapshot Data');

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final snapshotData = Provider.of<String>(context);

    return Text(snapshotData);
  }
}

Provider(
  create: (_) => 'Snapshot Data',
  child: MyWidget(),
);
