scale property

@override AnimationController scale

Press depth for the key's scale (the widget's press transform): the same as press on the way in; on release it follows the family's release spring (M3E 800/0.6, which may overshoot) while press — what painters read for corners and depth — may follow releaseAlt (M3E effectsDefault: corners never bounce; motion brief §2.3).

Implementation

@override
final AnimationController scale;
