【问题描述】：
import 'package:flutter/material.dart';
void main () {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
Widget build (BuildContext context) {
return MaterialApp(home: Text('Hello!'),);
}
}
这是我在 Flutter 上运行 main.dart 时的应用程序，出现以下错误。我已经使用模拟器正确安装了 Android Studio。我使用 VS Code 进行编辑。我将 git bash 作为终端运行。 Flutter 医生表示一切正常。
如何解决我的问题？

Gradle threw an error while downloading artifacts from the network主要与不稳定的互联网连接有关。您可以删除 Gradle 并重新安装吗？
