Flutter integration test that migrate from flutter_driver. How to attach existing app.

[tupobi]

I have a big problem that makes me headache:
I am using the integration_test which migrate from flutter_driver, cause flutter_driver has been deprecated.
But the flutter is a module contained by native app, and i want to execute flutter ui test.
How can i uese --use-existing-app, it appears:

Integration tests and unit tests cannot be run in a single invocation. Use separate invocations of flutter test to run integration tests and unit tests.

As a module, how to execute cmd:

flutter test integration_test

or

flutter test integration_test --use-existing-app

it appears:

Integration tests and unit tests cannot be run in a single invocation. Use separate invocations of flutter test to run integration tests and unit tests.

I want to attach the existing-app to make integration test.

The official doc doesn't help: https://flutter.dev/docs/testing/integration-tests

Please help me.
Thanks very very much.
