Constructors

SelectableController()

Properties

hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isTextSelected → bool: Returns true if text is selected in any selections.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
deselect({int? key}) → bool: If text is selected, deselects it. Returns true if the selection was updated to be deselected.
deselectAll() → bool: If text is selected, deselects it. Returns true if any selections were updated to be deselected.
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
getContainedText() → String: Returns a String containing the combined text of all render paragraphs contained in the Selectable. This can be used with selectWordAtIndex and selectWordsBetweenIndexes to select a word or words.
getCustomPainter({int? key}) → SelectionPainter?: Returns the selection painter, or null if none.
getCustomRectifier({int? key}) → (List<Rect> Function(List<Rect>)?): Returns the custom rectifier, or null if none.
getSelection({int? key}) → Selection?: Returns the selection, or null if a selection with the provided key does not exist. Note, if key is not provided, it returns the main selection (with key 0), which is guaranteed to be non-null.
hide({Duration? duration, int? key}) → bool: Hides the selection, if it is not already hidden. Returns true if the selection was updated to be hidden.
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
selectAll({int? key}) → bool: Attempts to select all the words in the text, if any. Returns true if successful.
selectWordAtIndex(int index, {int? key}) → bool: Attempts to select the word at index, returning true if successful.
selectWordAtPoint(Offset point, {int? key}) → bool: Attempts to select the word under point, returning true if successful.
selectWordsBetweenAnchors(SelectionAnchor start, SelectionAnchor end, {int? key}) → bool: Attempts to select the words between start and end selection anchors, returning true if successful.
selectWordsBetweenIndexes(int start, int? end, {int? key}) → bool: Attempts to select the words between start and end indexes, returning true if successful.
selectWordsBetweenPoints(Offset startPt, Offset endPt, {int? key}) → bool: Attempts to select the words between startPt and endPt, returning true if successful.
setCustomPainter(SelectionPainter? painter, {int? key}) → void: Sets the custom selection painter to be used to paint selections.
setCustomRectifier(List<Rect> rectifier(List<Rect>)?, {int? key}) → void: Sets the custom rectifier, which is used to convert the raw rectangles of selected text into the displayed selection rects.
toString() → String: A string representation of this object.
inherited
unhide({Duration? duration, int? key}) → bool: Unhides the selection, if it isn't already unhidden. Returns true if the selection was updated to be unhidden.
visitContainedSpans(bool visitor(SelectionParagraph paragraph, InlineSpan span, int index)) → bool: Walks the tree of render objects contained in the Selectable, and the sub-tree of each render paragraph's InlineSpan children in pre-order, calling visitor for each span that has content. A span has content if it is a TextSpan whose text property is not null, or it is a WidgetSpan.

Operators

operator ==(Object other) → bool: The equality operator.
