Sometimes getting `The analysis server shut down unexpectedly` when running `dart analyze .`

[nilsreichardt]

The FlutterFire CI (using GitHub Action) has sometimes the problem that the analysis crashes:

The analysis server timed out while shutting down.
No issues found!
The analysis server shut down unexpectedly.
Please report this at dartbug.com.

Running dart analyze . --fatal-infos in the monorepo not concurrently (melos exec -c 1 -- dart analyze . --fatal-infos) has a chance of 0.1% - 1% of getting this issue. Increasing the concurrently parameter also increases the chance of crashing the analysis server dramatically. Using melos exec -c 5 -- dart analyze . --fatal-infos has a 10% chance of getting this error.

• Output running melos exec -c 5 -- dart analyze . --fatal-infos (failed 10x of 100 runs): https://github.com/nilsreichardt/flutterfire/runs/6887637357?check_suite_focus=true

The FlutterFire CI is running with GitHub Action on ubuntu-latest. The Dart version is v2.17.3.
