Constructors

hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
hasSelection → bool: no setter
isCollapsed → bool: no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
state → SelectionState: no setter

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
batchUpdate(void fn()) → void: Executes fn with notifications suppressed, then notifies once.
clear() → void: Clears the selection
collapse() → void: Collapses the selection (removes the highlight)
dispose() → void: Discards any resources used by the object.
inherited
getRangeForNode(String nodeId) → ({String endFrag, int endOff, String startFrag, int startOff})?: Returns the selection range for a given node. Uses an internal cache so repeated lookups during a single sync pass (e.g. one per visible paragraph) are O(1) instead of O(visible).
isNodeSelected(String nodeId) → bool: True if the node is selected (partially or fully)
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
setPositionIndex(Map<String, int> index) → void
startSelection(String nodeId, String fragmentId, int offset) → void: Starts a selection (tap or start of drag)
toString() → String: A string representation of this object.
inherited
updateFocus(String nodeId, String fragmentId, int offset) → void: Updates the focus during drag
