[flutter_local_notifications_windows] use flutter test instead of dart test

[MaikuB]

Switched to flutter test to see if it helps improves output shown in the logs

Yeah I noticed. Not sure what is going on there. I recall having a similar problem but don't remember the solution. I think it had to do with the folder/scope that melos was able to run in. If you have ideas then let me know

[Levi-Lesches]

Nope, don't know what's going on here 🤷‍♂️

[MaikuB]

I'm going to abandon this PR for now as I don't have time to see what's going on. Verbose logs seemingly indicate the error is thrown by the Flutter tooling. I haven't been able to reproduce this as I'm having trouble as I'm trouble running the tests locally now. I did take the old DLL you had and used it on my local machine but that worked. Potentially this is to do with having Windows ARM when I run build.bat on my machine. The number of tests being run also looks off when run via GitHub as it should be 21 tests

[Levi-Lesches]

Yeah, I had a lot of issues as well. The tests are inherently flaky due to flutter insisting on multithreading them, whereas the underlying Windows API is inherently not thread-safe. I attempt to explain / debug a bit in bin/crash.dart and solve it with enableMultithreading(), but that didn't fix it 100%. When I had the issues, the test harness would segfault midway through the tests at random lines (even lines that just declare and don't even assign a variable). It's also why the tests all have a few retry attempts, it's to let a few tests fail, and then after the rest have finished, they get their own time to re-run.

Here's something more concrete though -- when I run these locally:

dart test --reporter compact  # rewrites a single line to show progress, works 21/21
dart test --reporter expanded  # each test on its own line, suddenly exits after 12 
dart test --reporter github  # the GitHub Actions text, suddenly exits after 12

These results aren't stable, and sometimes they do all work, but it's interesting that I was able to briefly recreate this problem locally. I'd say it's not worth fixing, and to let the exit code determine whether GitHub goes green or not
