lerp method Null safety

  1. @override
ThemeData lerp(
  1. double t
)
override

Returns the value this variable has at the given animation clock value.

The default implementation of this method uses the +, -, and * operators on T. The begin and end properties must therefore be non-null by the time this method is called.

In general, however, it is possible for this to return null, especially when t=0.0 and begin is null, or t=1.0 and end is null.

Implementation

@override
ThemeData lerp(double t) => ThemeData.lerp(begin!, end!, t);
