dartHostTestHandler property

The name of an interface generated for tests. Implement this interface and invoke [name of this handler].setup to receive calls from your real HostApi class in Dart instead of the host platform code, as is typical.

When using this, you must specify the --out_test_dart argument to specify where to generate the test file.

Prefer to use a mock of the real HostApi with a mocking library for unit tests. Generating this Dart handler is sometimes useful in integration testing.

Defaults to null in which case no handler will be generated.
