MiuixFloatingActionButton class

Miuix 风格的浮动操作按钮。对应 Kotlin FloatingActionButton。

在 Surface（shape=CircleShape, color=containerColor, shadowElevation）之上 用 defaultMinSize(60,60) 的 Box 居中放置内容。Flutter 端用 DecoratedBox

  • ShapeDecoration 复刻背景与阴影，MiuixPressable 复刻按压遮罩 （overlayColor = colors.onBackground，spring enter damping1.0/response0.2， exit damping0.95/response0.35）。

内容色注意：与 Kotlin 一致，FAB 不向 Surface 传 contentColor，因此内容色 继承 Surface 默认值 colors.onSurface（而非 onPrimary），通过 MiuixContentColor 向下传递，调用方提供的 MiuixIcon 默认会被 tint 成 onSurface。
