M3ESpring class

A serialisable description of a Material 3 Expressive spring.

damping is expressed as a damping ratio where 1.0 is critically damped (no overshoot) and values below 1.0 produce an expressive overshoot.

Properties

damping → double

Damping ratio. 1.0 is critically damped; lower values overshoot.

final

hashCode → int

Hash code for this spring.

no setter, override

runtimeType → Type
