SmoothSelectionRegionState class

State for SmoothSelectionRegion.

Delegates the standard selection APIs (selectAll, clearSelection, contextMenuButtonItems, contextMenuAnchors) to the underlying SelectableRegionState, so they behave identically. On top of that, it captures the inner SelectionContainer's delegate (a SelectionHandler + SelectionRegistrar) when the child subtree first builds, and exposes:

  • dispatchEvent — forward any SelectionEvent (e.g. a SelectAllSelectionEvent or ClearSelectionEvent) to the contained SelectionContainer, which fans it out to every text selectable in the subtree. This is the literal SelectionContainer + SelectAllSelectionEvent entry point.
  • registrar — the SelectionRegistrar that collects the text selectables in the subtree.
  • innerRegionState — the wrapped SelectableRegionState, for direct access to the full framework API.

Properties

context BuildContext
The location in the tree where this widget builds.
no setterinherited
contextMenuAnchors TextSelectionToolbarAnchors
The anchors used to position the text selection toolbar.
no setter
contextMenuButtonItems List<ContextMenuButtonItem>
The ContextMenuButtonItems for the platform-default selection menu.
no setter
hashCode int
The hash code for this object.
no setterinherited
innerRegionState SelectableRegionState?
The wrapped SelectableRegionState. null before first build.
no setter
mounted bool
Whether this State object is currently in a tree.
no setterinherited
registrar SelectionRegistrar?
The SelectionRegistrar that collects the text selectables in the subtree (the inner SelectionContainer's delegate). null before the child subtree has built.
no setter
runtimeType Type
A representation of the runtime type of the object.

widget SmoothSelectionRegion
The current configuration.

Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
build(BuildContext context) Widget
Describes the part of the user interface represented by this widget.
override
clearSelection() → void
Clears the current selection.
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
didUpdateWidget(covariant SmoothSelectionRegion oldWidget) → void
Called whenever the widget configuration changes.
override
dispatchEvent(SelectionEvent event) SelectionResult?
Dispatch an arbitrary SelectionEvent to the contained SelectionContainer's delegate.
dispose() → void
Called when this object is removed from the tree permanently.
override
initState() → void
Called when this object is inserted into the tree.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
selectAll([SelectionChangedCause cause = SelectionChangedCause.toolbar]) → void
Selects all the content in this region. Shows selection handles and, when cause is SelectionChangedCause.toolbar, the context toolbar.
selectParagraphAt(Offset globalPosition) → void
Selects the paragraph containing globalPosition and shows the selection handles and context toolbar.
selectWordAt(Offset globalPosition) → void
Selects the word at globalPosition and shows the selection handles and context toolbar — the programmatic equivalent of a native long-press at that point.
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.
