我最近在我的应用程序中升级了我的flutter版本.但是，当我想调试应用程序时，它显示了以下错误.

I have recently upgraded my flutter version in my app. But when I want to debug the application, it shows me the following error.

连接到服务协议时出错:HttpException:在收到完整的标头之前，连接已关闭，URI = http://127.0.0.1:50795/ws

我有一个临时的解决方法，我现在可以使用.当我将模拟器作为Pixel 3 Android 9. + Target(Q API)运行模拟器时，将引发以上异常.我制作了第二个模拟设备，Pixel 2 Android 9.0 Target(28 API)，这个目标可以正常工作.

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.

我还注意到，Pixel 2目标在磁盘上占用8.5GB，而Pixel 3目标仅占用1.4GB.这让我想知道Pixel 3目标是否缺少一些重要的东西.

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.
