我开始学习颤振并设置所有设置和其他内容。但是,当我在VS Code或Android Studio中启动项目时,出现此错误“连接服务协议时出错:HttpException:在接收到完整标头之前,连接已关闭,uri = http://127.0.0.1:60944/JpB2Y6E0g_g=/ws”,并且应用程序未启动,但是当我进入终端并说“ flutter run”,那么我仍然会遇到这个错误,但是应用程序启动了。但是,我无法直接运行应用程序,并且不能使用“ HOT-RELOAD”

我尝试清除频闪且关闭的防御程序或我拥有的任何防病毒程序以及Internet上的某些内容,但其中任何一个都无法帮助我

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(

        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Anasayfa'),
    );
  }
}

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 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.display1,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

我不能直接在终端ı上直接运行项目,而要在IDE上运行应用程序并使用“热重载”

尝试将您的Android版本从Q降级为Pie。 它在here
