SpringDescription class
Structure that describes a spring's constants.
Used to configure a SpringSimulation.
Constructors
- SpringDescription({required double mass, required double stiffness, required double damping})
-
Creates a spring given the mass, stiffness, and the damping coefficient.
const
- SpringDescription.withDampingRatio({required double mass, required double stiffness, double ratio = 1.0})
- Creates a spring given the mass (m), stiffness (k), and damping ratio (ΞΆ). The damping ratio describes a gradual reduction in a spring oscillation. By using the damping ratio, you can define how rapidly the oscillations decay from one bounce to the next.
- SpringDescription.withDurationAndBounce({Duration duration = const Duration(milliseconds: 500), double bounce = 0.0})
-
Creates a SpringDescription based on a desired animation duration and
bounce.
