Flutter SIGINT error on run all tests on visconde

When trying to "Run All Tests" from flutter/dart on VSCODE, I'm getting a SIGINT error and the test finish with "loading"on file, only the first one goes ok. The problem is that the same thing does not happen if I run the tests one by one.

loading /Users/marciomontenegro/Documents/Projects/mel/test/domain/usecases/sign_in_test.dart:
