EditorZoomMixin<T extends StatefulWidget> mixin

A mixin that provides zoom-related behavior for image or content editors.

This includes logic for double-tap detection, zoom control, and reset actions. It expects a GlobalKey reference to an ExtendedInteractiveViewerState implementation.

inherited
build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
inherited
deactivate() → void
Called when this object is removed from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void

inherited
detectDoubleTap(PointerDownEvent details) → bool

didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant T oldWidget) → void
Called whenever the widget configuration changes.
inherited
dispose() → void
Called when this object is removed from the tree permanently.
override
handleDoubleTap(BuildContext context, PointerDownEvent details, ZoomConfigs configs) → void
Handles a confirmed double-tap gesture and performs a zoom action.
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
onPointerUp(PointerUpEvent event) → void

reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
resetZoom() → void

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
zoomTo({Offset? offset, double? scale}) → void
Programmatically zooms the editor to a given offset and/or scale.

Operators

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