Methods

activate() → void: Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
alignmentFromGlobal(Offset globalPosition) → double: Maps a global pointer position to alignment in -1, 1 with rubber-band resistance applied at the edges.
inherited
build(BuildContext context) → Widget: Describes the part of the user interface represented by this widget.
override
computeTabAlignment(int index) → double: Maps a tab index to horizontal alignment in -1, 1.
inherited
deactivate() → void: Called when this object is removed from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
didChangeDependencies() → void: Called when a dependency of this State object changes.
inherited

override
dispose() → void: Called when this object is removed from the tree permanently.
inherited
initState() → void: Called when this object is inserted into the tree.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyTabChanged(int index) → void: Called once per gesture lifecycle when the active tab should change.
override
onBarDragCancel() → void: onHorizontalDragCancel — snap to nearest tab without velocity.
inherited
onBarDragDown(DragDownDetails d) → void: onHorizontalDragDown — marks pointer as pressed for jelly activation.
inherited
onBarDragEnd(DragEndDetails d) → void: onHorizontalDragEnd — snap to target tab with velocity fling support.
inherited
onBarDragStart(DragStartDetails d) → void: onHorizontalDragStart — drag confirmed; lock position to pointer.
inherited
onBarDragUpdate(DragUpdateDetails d) → void: onHorizontalDragUpdate — track pointer during drag.
inherited
onBarTapDown(TapDownDetails d) → void: onTapDown — selects tab on tap, including repeat-tap on the active tab.
inherited
reassemble() → void: Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
setState(VoidCallback fn) → void: Notify the framework that the internal state of this object has changed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringShort() → String: A brief description of this object, usually just the runtimeType and the hashCode.
inherited
updateTabAlignIfNeeded(int oldTabIndex, int oldTabCount) → void: Call from didUpdateWidget when tabIndex or tabCount may have changed.
