今天我在测试我的应用程序的新功能时遇到了这个错误

我用谷歌搜索并找到了另一个关于该问题的论坛条目。他们说出现错误，确认热重载。他们说我应该停止应用程序并重新运行它，但它并没有解决错误。代码来自教程，一切正常。 这是我的代码：

import 'package:flutter/material.dart';
import 'package:share/share.dart';

class DetailScreen extends StatelessWidget {

  const DetailScreen(this.title, this.done);
  final String title;
  final bool done;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: done ? Colors.green : Colors.red,
      appBar: AppBar(
        title: Text('Detail Screen'),
        backgroundColor: Colors.transparent,
      ),
      body: Padding(
        padding: EdgeInsets.symmetric(vertical: 70),
        child: Column(
          mainAxisAlignment: MainAxisAlignment.spaceAround,
          children: <Widget>[
            Expanded(
                child: Container(
                    padding: EdgeInsets.all(20),
                    alignment: Alignment.center,
                    child: Text(
                      done ? 'Das hast du schon erledigt:' : 'Das musst du noch machen:',
                      style: TextStyle(fontSize: 20, color: Colors.white), textAlign: TextAlign.center,))
            ),
            Expanded(
                child: Container(
                    alignment: Alignment.center,
                    child: Text(title, style: TextStyle(fontSize: 50, color: Colors.white)))
            ),
            Expanded(
              child: Row(
                mainAxisAlignment: MainAxisAlignment.spaceAround,
                children: <Widget>[
                  IconButton(
                    iconSize: 60,
                    onPressed: () {
                      String message;
                      if (done) {
                        message = 'Ich habe folgendes Todo erledigt: ' + title;
                      } else {
                        message = 'Das muss noch erledigt werden: ' + title;
                      }
                      Share.share(message);
                    },
                    icon: Icon(Icons.share, color: Colors.white),
                  ),
                  IconButton(
                    iconSize: 60,
                    onPressed: () => Navigator.pop(context),
                    icon: Icon(done ? Icons.check : Icons.close, color: Colors.white),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

哦，有时 IntelliJ 会将我转发到名为“binding.dart”的类并标记completer.complete(reply);。但我不知道，它会对我说什么。我用于分享功能的包是this

正如你所说的

我用谷歌搜索并找到了另一个关于该问题的论坛条目。他们说出现错误，确认热重载。他们说我应该停止应用程序并重新运行它，但它并没有解决错误。代码来自教程，一切正常。

不适合你尝试运行 flutter clean 和 flutter pub get
