'CupertinoTextField' is not a subtype of type 'TextField'

[cdm2012]

The internal functionality of the BaseIntegrationTest.enterText defaults to EditText. I'm currently using a CupertinoEditText and it is failing with the following message/stack.

I/flutter (11696): The following _CastError was thrown running a test:
