Summary: The user is experiencing an error during Dart analysis, where the "dart:async" library is missing. The error occurs despite restarting, cleaning the cache, updating packages, and upgrading the IDE. The user has provided their project repository, version information, and a detailed log of the error.

[mraleph]

Try close IDE, purge analysis driver cache by doing mv ~/.dartServer ~/.dartServer.bak and start IDE again.

If that helps then something is wrong with analysis driver cache got somehow corrupted and might be of interest to analyzer team.

@mraleph Your advice didn't work, but I discovered that downgrading to Flutter version 3.22.0 solved the issue.

[mjablecnik]

Version where it works is:

martin at Martins-MacBook-Air startup_project >>> flutter --version
Flutter 3.22.0 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 5dcb86f68f (5 months ago) • 2024-05-09 07:39:20 -0500
Engine • revision f6344b75dc
Tools • Dart 3.4.0 • DevTools 2.34.3

[mjablecnik]

I created a specific branch in my project: https://github.com/mjablecnik/startup_project/tree/dart-analysis-issue where I had the problem if you will need it for test.
