ThreePointCubic class Null safety
A cubic polynomial composed of two curves that share a common center point.
The curve runs through three points: (0,0), the midpoint, and (1,1).
The Curves class contains a curve defined with this class: Curves.easeInOutCubicEmphasized.
The ThreePointCubic class implements third-order Bézier curves, where two curves share an interior midpoint that the curve passes through. If the control points surrounding the middle point (b1, and a2) are not colinear with the middle point, then the curve's derivative will have a discontinuity (a cusp) at the shared middle point.
