Integration tests don't finish on failure

[HugoCSWork]

Describe the bug

Currently if you run integration tests with catcher 2 wrapped around the application on a failure the tests don't finish but just get stuck. This was not occurring on the original catcher. I have created a demo project to demonstrate the issue.

To Reproduce

Steps to reproduce the behavior:

1. Clone https://github.com/HugoCSWork/catcher_2_integration_test_bug
2. run the integration test flutter test integration_test/main_test.dart
3. Test will fail as expected but will cause the integration tests to get stuck

Expected behavior

Test will complete in terminal showing one integration test failure

Device

• OS: MacOS and Linux
• catcher_2 version: 1.0.0

Checklist

• I have read and followed the entire README and it has not provided the solution I need.
• I have provided all the information I can (incl. auth URL etc.)

Thanks for the MRE! I will take a look at it in a few hours when I am home.
I suspsect that this might be very related to #10 and I fear that some internal changes inside Flutter's runApp function are the real culprit in both cases.
In the mean time, can you observe the same behaviour in Flutter 3.13.7 or even older (like 3.13.0 and 3.10.7 or something?)

[HugoCSWork]

Thanks for the quick response! I've done some quick testing with FVM using version 3.13.7 and 3.10.7 but am still experiencing the same issue.

When using the previous catcher it was on flutter version 3.7.8 but that is incompatible with catcher 2.

Alright, thanks for the testing and reporting back! I will see what I can do then. Catcher 2 has only very few internal changes to Catcher, so it will most likely be some change between Flutter 3.7.x and Flutter 3.10.x. Maybe, I will find something suspicious.

I was not able to reproduce this exact issue, because I had another one.
Please see whether the test fails properly on your machine in https://github.com/HugoCSWork/catcher_2_integration_test_bug/pull/1

I have added two parameters to Catcher2Options which can be used to define additional behaviour that should be executed when an error is caught by this package.
Integration tests rely on a specific onError behaviour which can be inherited this way.
Maybe, it would also be nice to have another parameter which can be used to indicate that the current value of onError should be used.

The fix should now be available as part of version 1.0.1

Thank you for getting this sorted so quickly!
