FTappable class
An area that responds to touch.
It is typically used to create other high-level widgets, i.e., FButton. Unless you are creating a custom widget, you should use those high-level widgets instead.

Properties
- autofocus → bool
-
True if this widget will be selected as the initial focus when no other node in its scope is currently focused.
final
- behavior → HitTestBehavior
-
The tappable's hit test behavior. Defaults to HitTestBehavior.translucent.
final
-
builder
→ ValueWidgetBuilder<
Set< WidgetState> > -
The builder used to create a child with the current state.
final
- child → Widget?
-
The child.
final
- excludeSemantics → bool
-
Whether to replace all child semantics with this node. Defaults to false.
final
- focusedOutlineStyle → FFocusedOutlineStyle?
-
The style used when the tappable is focused. This tappable will not be outlined if null.
final
- focusNode → FocusNode?
-
An optional focus node to use as the focus node for this widget.
final
- hashCode → int
-
The hash code for this object.
