Running the tests with

flutter test --coverage

should generate a file

/coverage/Icov.info

Which holds the information you need.

You can now extract infos from the file in various methods as described here

In a easy way, you can determine the test coverage threshold using this package https://pub.dev/packages/dlcov

usage example:

dlcov --lcov-gen="flutter test --coverage" --coverage=100

--lcov-gen Generate the lcov.info file

--coverage=100 To determine if the test coverage threshold is 100%
