mocktail could offer string diffs on call failures?

[eseidel]

For long strings it can be very hard to figure out how to match calls exactly. e.g.:

      verify(
        () => logger.info('''

Your next step is to upload the app bundle to the Play Store:
build/app/outputs/bundle/release/app-release.aab

Or distribute the apk:
build/app/outputs/apk/release/app-release.apk

For information on uploading to the Play Store, see: 
${link(uri: Uri.parse('https://support.google.com/googleplay/android-developer/answer/9859152?hl=en'))}
'''),

I get the message:

I'm clearly very close, but not quite right yet. Mocktail could theoretically detect this and offer me a string difference to help see where my error is. 🤷 That may be out of scope for mocktail though.

package:test has some decent string diffing code (I even used it in a recent fun project):

Turns out it was just me missing a "lightCyan.wrap" around my apk/aab paths in the above. 🤷

The matcher "equals" has some nice string diff outputs (as well as for collections). Mocktail could it use its "describeMismatch" for this
