Sprung is an easy-to-consume Curve that uses real physics equations to drive your animations.

AnimatedContainer( curve: Sprung(), /// ... ),
Sprung() also supports three damping curves,
AnimatedContainer( curve: Sprung( damped: Damped.under ), /// ... ),
Note: Sprung is critically damped by default.
Based on Physics
Using Newton's Second Law of Motion, Hooke's Law, and velocity based damping, we implement the following equation in three finite cases.
Sprung exceeds Flutter specifications for curves by guaranteeing an error less than
1e-6. This amounts to a
0.0019px jitter at the beginning or end of a
