MiuixNavigationRail class

适合宽屏使用、可选展开控制器的 Miuix 导航栏。

state 为空时使用经典折叠布局且不显示切换按钮；非空时，栏宽、项目布局、 选中背景和字号共享同一条弹簧动画。项目通过 MiuixNavigationRailItem 自动取得动画信息。背景先于安全区留白绘制，因此可延伸到起始侧系统区域。

final
defaultWindowInsetsPadding → bool
final
expandContentDescription → String
final
expandedItemVerticalPadding → double
展开态项目上下内边距。默认 MiuixNavigationRailDefaults.expandedItemContentVerticalPadding（14）。 减小它可直接降低展开态每项高度。

final
expandedWidth → double
final
hashCode → int
The hash code for this object.
no setterinherited
final
iconSize → double
项目图标尺寸。默认 MiuixNavigationRailDefaults.iconSize（28，原版值）。 减小它会同时降低项目高度（折叠/展开态都变矮）。
final
itemVerticalPadding → double
折叠态项目上下内边距。默认 MiuixNavigationRailDefaults.itemVerticalPadding（12）。
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
labelFontSize → double
折叠态标签字号。默认 MiuixNavigationRailDefaults.labelFontSize（12）。
final
minWidth → double
final
runtimeType → Type
A representation of the runtime type of the object.
