Constructors

ExpandableWidget.manual({required bool expand, required TickerProvider? vsync, required Widget child, Duration animationDuration = const Duration(milliseconds: 150), Alignment alignment = Alignment.topCenter, Key? key})
Manual control Show and hide child completely.
const
ExpandableWidget.maxHeight({Key? key, Color? arrowColor, double arrowSize = 24, ArrowBuilder? arrowWidgetBuilder, double? arrowWidgetHeight, Duration animationDuration = const Duration(milliseconds: 150), required Widget child, double maxHeight = 100.0, bool expand = false, Alignment alignment = Alignment.topCenter})
Auto control Collapse child to max-height With a arrow at the bottom. If the child's height < maxHeight, then will show child directly
