This fix is good. Thanks for your contribution! Might make sense to add a test to make sure the original issue is gone too (i.e. tap the text, check the value changes). Would you mind doing that?

An existing RadioListTile test verifies that onChanged is called by both a label and a radio tap. I added a test to verify the new selection after a rebuild.

My logic for getting find to match a Radio<_T> feels awkward. Do you see a less clunky approach?

@Hixie Anything else needed to get this one through?

@jslavitz @Hixie Is there anything I can do to help besides keeping the changes up to date with master?
