我最近在我的应用中升级了我的 flutter 版本。但是当我想调试应用程序时，它会显示以下错误。

连接到服务协议(protocol)时出错:HttpException:在收到完整 header 之前连接已关闭，URI = http://127.0.0.1:50795/ws

有没有人在升级flutter版本后遇到同样的问题？如果有任何解决方法，请分享。

最佳答案

现在这个问题在 github 上打开 https://github.com/flutter/flutter/issues/32587

暂时您可以通过切换到物理设备而不是模拟器来解决此问题 How to test android apps in a real device with Android Studio?

I've got a temporary work around, which I can use for now. The exception above is thrown when I run the emulator as a Pixel 3 Android 9.+ Target (Q API). I made up a second emulated device, a Pixel 2 Android 9.0 Target (28 API), and this target works fine.

I'm also noticing that the Pixel 2 target takes up 8.5GB on Disk, while the Pixel 3 target only takes up 1.4GB. It makes me wonder if the Pixel 3 target is missing some important things.
