flutter - 如何点击并将调试文本更改为开发右上角的红色调试横幅？

Question

我正在尝试将横幅“调试”的名称更改为“开发”、“阶段”、“”、“”、“” .以编程方式

我想在单击该调试横幅时执行一些操作。
我想覆盖该调试横幅的所有功能。
我是否只需要使用这个创建一个新的自定义横幅:
https://api.flutter.dev/flutter/widgets/Banner-class.html
或者有什么办法。
该调试横幅是否仅在 Debug模式下显示？是否可以使多用途。
提前致谢。

你可以试试这个解决方案它对我有用

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

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

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        Scaffold(
          appBar: AppBar(
            title: Text(widget.title),
          ),
          body: Center(
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                Text(
                  'You have pushed the button this many times:',
                ),
                Text(
                  '$_counter',
                  style: Theme.of(context).textTheme.headline4,
                ),
              ],
            ),
          ),
          floatingActionButton: FloatingActionButton(
            onPressed: _incrementCounter,
            tooltip: 'Increment',
            child: Icon(Icons.add),
          ), // This trailing comma makes auto-formatting nicer for build methods.
        ),
        Align(
          alignment: Alignment.topRight,
          child: Container(
            padding: EdgeInsets.only(top: 55, right: 50),
            child: Banner(
              message: "Custom",
              location: BannerLocation.bottomStart,
            ),
          ),
        ),
      ],
    );
  }
}
