Actually, the asserts that I thought protected this change, don't actually do what I thought they did, so this is actually changing the way themes work. We can try again to make it non-nullable once we remove the deprecated APIs. Closing this. |

Description
This changes the
TextThemevalues for themes to all be non-nullable instead of nullable. The constructor allows for either the legacy names or the new names to be used, but in the end, because of asserts, one or the other of them must be defined. Because of that, it's allowable to provide a default-constructedTextStyleas a fallback if both are null (which can't happen), so that the values can all be non-nullable.Tests
