Dart-Code: [Analyser] Error [ERR_STREAM_DESTROYED]: Cannot call write after a stream was destroyed

Hi,

I encounter this issue quitte a lot recently and one of my friend also :

Hello devs! I managed to solve this by doing the following steps:

Restarting VSCode,
Running “flutter clean” on the terminal,
and right after I ran the application!

It was a success! I hope I can help them 😀

The original issue linked above was accidentally re-introduced in the Dart SDK and has recently been re-fixed (see https://github.com/dart-lang/sdk/issues/40348#issuecomment-689468824). That fix hasn’t made Flutter’s stable channel yet, so I suspect you’re seeing the same thing.

I’m also facing this issue. The Dart Analyzer has crashed much more frequently the last month or two, not exactly sure when it started. Using flutter daily and I’m on the beta branch of Flutter (currently 1.12.13+hotfix.6). It seems like it crashes every time I start my flutter app now.

I’m using VS Code on Windows but I cannot install the vsix posted above. I get this error when I try to install the vsix:

The log from the dart analyzer seems very similar to the one from Todd above:
