TextTheme.debugFillProperties and Typography.debugFillProperties decide which values to report by comparing them against a default. Both defaults were out of date:

  • TextTheme compared against Typography.material2018(...).black
  • Typography compared against Typography.material2014()

This PR:

  • compares TextTheme styles against ThemeData.fallback().textTheme.
  • compares Typography text themes against ThemeData.fallback().typography. This matches how ThemeData.debugFillProperties already reports typography.
  • Treats null TextTheme styles as default. When a TextTheme is merged into a ThemeData, a null style falls back to the default style, so it shouldn't be reported as a difference.

Fixes flutter/flutter#194981

Code Review

This pull request updates TextTheme.debugFillProperties and Typography.debugFillProperties to use the default ThemeData text theme and typography instead of hardcoded defaults. It also refactors the property addition logic in TextTheme to reduce boilerplate and adds corresponding unit tests to verify the behavior of these debug properties. I have no feedback to provide.
