android - Appbar上的Flutter定位超链接

是否可以在应用栏上放置使用url_launcher创建的超链接？在这里，我的意思是https://ibb.co/X28TzNN“Sito Web”的屏幕是我想要更改位置的超链接，需要将其移动到红色圆圈中。这是我的AppBar

class BackgroundImage extends StatelessWidget{
  final Widget body;
  BackgroundImage({this.body});
    @override
    Widget build(BuildContext context){
      return Scaffold(
        appBar: AppBar(
          elevation: 0,
          title: Text('Blumax', style: TextStyle(
            fontWeight: FontWeight.w500,
            fontFamily: 'DancingScript',
            fontSize: 40
          ),),
          centerTitle: false,
        ),
        body: Stack(
          children: <Widget>[Container(
          decoration: BoxDecoration(
            image: DecorationImage(image: AssetImage("assets/whiteimage.jpg"), fit: BoxFit.cover),
          ),
        ),
          body
        ]
      )
    );
  }
}

这就是我为将文本放在右上角所做的

  Widget build(BuildContext context) {
    return InkWell(
      child: Container(
        alignment: Alignment(0.9, -1.0),
      child: Text(
        _text,
        textAlign: TextAlign.right,
        style: TextStyle(
          fontFamily: 'RobotoMono',
          fontSize: 20,
          color: Colors.white,
          decoration: TextDecoration.underline),
      )),
      onTap: _launchURL,
    );
  }
}

最佳答案

@andrea，您不需要使用InkWell /容器。您可以通过简单的按钮在appBar中使用 Action ，然后尝试类似的操作，

class MyAppState extends State<MyApp> {
  String _text = 'Link';
  String _url = 'https://www.test.com';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        home: Scaffold(
            appBar: AppBar(
              title: Text('Test'),
                actions: <Widget>[
                  FlatButton(
                    child: Text(_text, style: TextStyle(fontSize: 18.0, color: Colors.white)),
                    onPressed: _launchURL,
                  ),
                  IconButton(icon: Icon(Icons.more_vert, color: Colors.white), onPressed: (){})
                ]
            ),
            body: Padding(
                  padding: EdgeInsets.all(20.0),
                  child: Center(
                    child: Text('')
                  )
                  )
            )
            );
  }

  _launchURL() async {
    if (await canLaunch(_url)) {
      await launch(_url);
    } else {
      throw 'Could not launch $_url';
    }
  }
}
