text_field_test.dart test hangs when run with --machine #54917
Description
When I try to run flutter test test/material/text_field_test.dart in the flutter repo from packages/flutter, it works, but when I run it from the IDE, or on the command line with flutter test --machine test/material/text_field_test.dart, it hangs after running the tests, and throws an exception:
NoSuchMethodError: The method 'handleFinishedTest' was called on null.
Receiver: null
Tried calling: handleFinishedTest(Instance of 'ProcessEvent')
I can't tell if this is because there's something funky with the test, or with the tool.
