Finally managed to get a minimal repro. When the package under test has a *dev* dependency on a package with native assets, it works under `dart test` but not `test_with_coverage`.

The issue is that `test_with_coverage` runs tests through `dart run` instead of `dart test`. In fact I can repro this running the test through `dart run test/foo_test.dart` manually, without using...

Ah ok. Defaulting to not building the dev deps in `dart run` makes sense I guess. But we probably need a way of overriding that, like a flag we can...

Fair enough. That approach would be compatible with solution 6. In our interop team meeting Hossein and I were leaning towards solution 6. Hossein is going to work on a...

Ok, so we update ffigen to optionally generate mocks. Then change my example above to: ```dart test('Testing Foo', () { // Foo is an ObjC class that has an FFIgen...
