FlippedCurve class
A curve that is the reversed inversion of its given curve.
This curve evaluates the given curve in reverse (i.e., from 1.0 to 0.0 as t increases from 0.0 to 1.0) and returns the inverse of the given curve's value (i.e., 1.0 minus the given curve's value).
This is the class used to implement the flipped getter on curves.
This is often useful with CurvedAnimation.reverseCurve.
See also:
- Curve.flipped, which provides the FlippedCurve of a Curve.
- ReverseAnimation, which reverses an Animation rather than a Curve.
- CurvedAnimation, which can take a separate curve and reverse curve.
