When flutter web runs, it opens window without content - flutter

When I run flutter run -d chrome, it opens a blank window.

Have you tried with the available flutter packages? If not, then try with flutter_desktop_audio_recorder or record. Both of them supports Windows.

But unfortunately it's not fixed yet. Maybe this is a bug.

Flutter Project does not start

When I want to start my project the following message appears
Launching lib\main.dart on Chrome in debug mode...
Then Google Chrome starts but it doesn't show anything except a white screen.
I have already reinstalled flutter, Dart SDK and VS Code.

Flutter run -d all Won't start chrome

flutter run -d all will start the application on android and iOS Simulators but won't start chrome.
Any Ideas?
Here is my flutter doctor output if that matters:

I think this is intended behavior, the same way that if you type flutter run -d all when no other device than Chrome and the web server are available, it outputs No devices found. I guess it's because the web support is still experimental. The only way is flutter run -d chrome.
