Analyzer performance degrades when using code generation

[KlausJokisuo]

Currently, if we have a huge project with multiple files that need to be generated, the analyzer performance degrades.

• When the code generation is completed there is a high chance that there are "incorrect" analyzer errors, usually restarting the analyzer fixes this issue. Another thing that fixes some of the issues is re-syncing the files on IntelliJ
• Regarding IntelliJ Dart/Flutter plugin there are also some issues, which I think are related to analyzer. E.g. when using the Flutter plugin to wrap a Widget around another widget or when applying a quick-fix. What happens is that you can do it, but nothing actually happens. If you re-try a couple of times, then it works again. I started noticing this bug after this commit: https://github.com/JetBrains/intellij-plugins/commit/b7caf4c5a4e10187e6f4386f0f7548756b37f71d.

This tracker is for issues related to:

• Analyzer

Some other pieces of the Dart ecosystem are maintained elsewhere. Please file issues in their repository:

• Dart IntelliJ plugin: https://github.com/JetBrains/intellij-plugins/tree/master/Dart
• Flutter IntelliJ plugin: https://github.com/flutter/flutter-intellij

If you aren't sure, file the issue here and we'll find the right home for it. In your issue, please include:

• Dart SDK Version (dart --version) 2.17.1
• Whether you are using Windows, MacOSX, or Linux (if applicable) MacOSX (M1)

@scheglov Mostly as an FYI. It sounds like analyzer might have problems when there are frequent watch events being generated.
