CalseeKey class

A button drawn by the current theme's key renderer, with its spring press motion: Claymorphism squishes, NeoPOP extrudes, Liquid Glass inflates, and so on.

role picks which of the theme's key faces it wears: KeyRole.digit for ordinary keys, KeyRole.equals for the one primary action (the theme's accent), KeyRole.operator and KeyRole.function for secondary ones. Size it like any widget; it fills its box.

With onLongPress, a hold fills the face and fires after KeyPressMotion.holdDuration.

Constructors

CalseeKey({required KeyRole role, required CalseeKeyBuilder builder, required String semanticLabel, VoidCallback? onPressed, VoidCallback? onLongPress, bool haptics = true, int artSeed = 0, Key? key})
A key whose content comes from builder.
const
CalseeKey.icon(IconData icon, {required KeyRole role, required String semanticLabel, String? label, VoidCallback? onPressed, VoidCallback? onLongPress, double sizeFactor = 0.42, bool haptics = true, Key? key})
A key showing icon, with an optional label under it.
factory
CalseeKey.text(String text, {required KeyRole role, VoidCallback? onPressed, VoidCallback? onLongPress, String? semanticLabel, double sizeFactor = 0.4, bool haptics = true, Key? key})
