如何将区块添加到StatelessWidget屏幕

class BlockWidget extends StatefulWidget {
  @override
  _BlockWidgetState createState() => _BlockWidgetState();
}

class _BlockWidgetState extends State<BlockWidget> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Column(
        children: [
          Text(
            'This is a block',
            style: TextStyle(fontSize: 16),
          ),
          Image.network('https://example.com/block-image.jpg'),
        ],
      ),
    );
  }
}

class HomeScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: Column(
        children: [
          Text('Welcome to the Home Screen'),
          BlockWidget(),
        ],
      ),
    );
  }
}
