MaterialSpringMotion class

Material Design 3 spring motion tokens for expressive design system.

This class provides predefined spring motion tokens that follow the Material Design 3 motion guidelines for creating expressive and natural animations. The tokens are organized into two categories:

• Spatial: For animating position, size, and layout changes
• Effects: For animating visual properties like opacity and color

Each category has three speed variants: fast, default, and slow.

Methods

copyWith({double? damping, double? stiffness, bool? snapToEnd}) → MaterialSpringMotion

Creates a new SpringMotion with the same properties as this one, but with the specified description and snapToEnd.

override

createSimulation({double start = 0, double end = 1, double velocity = 0}) → Simulation

Creates a simulation for this motion.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

Returns a string representation of this object.

Operators

operator ==(Object other) → bool

Equality operator for SpringMotion.
