HoverBuilder class
A widget that detects mouse hover events and notifies its child. This widget is useful when you want to change the appearance of a widget when the mouse hovers over it.
Example: HoverBuilder( builder: (context, hovering, child) { return AnimatedContainer( duration: const Duration(milliseconds: 200), width: 100, height: 100, color: hovering ? Colors.orange : Colors.red, alignment: Alignment.center, child: child, ); }, child: const Text('Hover Me'), ),

Properties
- builder → HoverWidgetBuilder
-
Builder that builds the child. This builder will be called whenever the
hover state changes. The
hovering
parameter indicates whether the widget is currently being hovered or not.final - child → Widget?
-
Child of this widget. This child will not be rebuilt when the hover
state changes. It is recommended to use this child for static content
that does not change when the hover state changes.
final

-
Refers to the MouseRegion.cursor property.
final
- enabled → bool
-
Whether the hover effect is enabled or not. If set to false, the cursor
will be MouseCursor.defer and the hover effect will not be applied.
final
- hashCode → int
-
The hash code for this object.
