DecayConfig class

Per-state release-time decay model.

State semantics match FrictionConfig: applied based on rect position (in-display vs past-display) and direction (extending vs retracting). The release trajectory consults this 4-state map per phase, picking the Decay whose zone the segment occupies.

Constructors

DecayConfig({Decay? extending, Decay? extendingPastDisplay, Decay? retracting, Decay? retractingPastDisplay, Settle? settle})

const

DecayConfig.byDirection({required Decay? extending, required Decay? retracting, Settle? settle})

Group by direction: extending covers both in-display and past-display extending; retracting covers both retracting states.

const

DecayConfig.byZone({required Decay inDisplay, required Decay pastDisplay, Settle? settle})

Group by zone: inDisplay covers both extending and retracting inside the display; pastDisplay covers both once the edge has crossed.

const

DecayConfig.uniform(Decay decay, {Settle? settle})

Same Decay for all four states. settle is independent.

Properties

extending → Decay?

final

extendingPastDisplay → Decay?

final

hashCode → int

The hash code for this object.

no setter, inherited

retracting → Decay?

final

retractingPastDisplay → Decay?

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

settle → Settle?

Rubber-back motion after decay ends. The simulation is driven by Settle.simulationAt so velocity stays continuous from the decay's end. Null = use package default (FrictionSettle).
