analyzing takes for too long when writing any code in flutter !

Describe the bug i am on ubuntu 20.04 and iam using dart and flutter with vs code and whenever i ever write any complex code it starts analyzing and it does that like non-stop over and over again so i have to write the code in a pad or whatever and paste it in vscode which is inconvenient at all ! To Reproduce Steps to reproduce the behavior: just by writing any complex code like Stream<List<NewsModel>> newsStream or using dartz like this Future<Either<T1,T2>>

Expected behavior it is expected to compile and analyze it as fast as possible in every code i write . Screenshots

Versions :

• VS Code version: 1.57.1
• Dart extension version: 3.23.1
• Dart/Flutter SDK version: Dart : 2.13.1 /Flutter : 2.2.1

Can you reliably reproduce this? If so, can you try:

• delete the problematic code from the file and Save
• enable the analysis server instrumentation log
• restart VS Code
• wait for initial analysis to completely finish
• type the code that triggers the issue
• take a copy of that log file

If there’s nothing sensitive in the log file, you can share it in a gist or email it to me at [e-mail]. Otherwise, let me know and I can give you some instructions to find the useful parts from the log that might help understand what’s wrong.

There were some fixes in Flutter 2.2.2 that solve issues like this, however my understanding is that they only apply to macOS, so I don’t think it’s that - although it may be worth upgrading to that version just to be sure.

Thanks!

I’ve filed https://github.com/dart-lang/sdk/issues/46505 about this as this appears to be a parser issue. I’ll close this one in favour of there, as it’s not something that can be fixed in the VS Code extension. Thanks!
