连接已关闭：javax.net.ssl.SSLException：标签不匹配

Question

有没有人遇到过这个错误？ 我是 flutter 的新手，在运行我丢失的 flutter 的示例文件时有什么问题吗？ 堆栈跟踪给了我 3 个错误，例如：线程“主”javax.net.ssl.SSLException 中的异常：连接已关闭：javax.net.ssl.SSLException：标记不匹配！ 和引起：javax.net.ssl.SSLException：标签不匹配！ 和引起：javax.crypto.AEADBadTagException：标签不匹配！

这是我的堆栈跟踪

以下文件是“main.dart”

    import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {   @override   Widget build(BuildContext context) {

  final String title;

            ),
            Text(

当我运行任何项目时，我面临同样的错误堆栈。 任何帮助将不胜感激。 谢谢：）

Answer 1

尝试更新 android studio 和对应的 flutter 和 dart sdks。 然后 go 进入 sdk 管理器并更新构建工具。 重新启动您的 IDE 和模拟器，flutter 现在应该可以工作了。

Answer 2
