Flutter:如何使用Navigator PushNamed发送屏幕构造函数所需的参数

final Map<String, WidgetBuilder> routes = {
  '/screen1': (BuildContext context) => Screen1(),
  '/screen2': (BuildContext context) => Screen2(),
};

void main() {
  runApp(MaterialApp(
    routes: routes,
    home: HomeScreen(),
  ));
}

Navigator.pushNamed(context, '/screen1', arguments: {'param1': 'value1', 'param2': 'value2'});

class Screen1 extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final Map<String, dynamic> arguments = ModalRoute.of(context).settings.arguments;
    final String param1 = arguments['param1'];
    final String param2 = arguments['param2'];

    // 使用参数构建屏幕
    return Scaffold(
      appBar: AppBar(
        title: Text('Screen 1'),
      ),
      body: Center(
        child: Column(
          children: [
            Text('Parameter 1: $param1'),
            Text('Parameter 2: $param2'),
          ],
        ),
      ),
    );
  }
}
