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 directlyconst - ExpandableWidget.showHide({Key? key, Color? arrowColor, double arrowSize = 24, ArrowBuilder? arrowWidgetBuilder, double? arrowWidgetHeight, Duration animationDuration = const Duration(milliseconds: 150), required Widget child, bool expand = false, Alignment alignment = Alignment.topCenter})
-
Auto control
Show and hide child completely
With a arrow at the bottom.
