Use case

Tests may take an hour or more to run, especially in a CI environment with limited resources. If there was an argument for flutter test (similar to pytest's --exitfirst), then a failure that happens within the first 10 minutes, etc. can stop further test execution. This can allow developers to fix tests and re-run them locally, saving a lot of time and money in a CI.

Proposal

Add an argument such as flutter test --exit-first that will stop further text execution when a failure is hit.
