CurveTween class

An Animatable that applies a Curve to the input value.

This does not interpolate between two values; it merely transforms the input double through a curve. Chain it with a Tween to get curved interpolation:

final curved = CurveTween(curve: Curves.easeIn);
final tween = Tween<double>(begin: 0, end: 100);
final animatable = curved.chain(tween);
