如何移除flutter app中的慢模式标签

Question

Answer 1

在命令行中：

flutter run --release

如果要调试并且只隐藏功能区，请设置Material小部件的DebugShowCheckedModeBanner属性

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}
