ThemeDataTween constructor Null safety

ThemeDataTween(
  1. {ThemeData? begin,
  2. ThemeData? end}
)

Creates a ThemeData tween.

The begin and end properties must be non-null before the tween is first used, but the arguments can be null if the values are going to be filled in later.

Implementation

ThemeDataTween({ super.begin, super.end });
