AppKitView class
Widget that contains a macOS AppKit view.
Embedding macOS views is an expensive operation and should be avoided where a Flutter equivalent is possible.
The platform view's lifetime is the same as the lifetime of the State object for this widget. When the State is disposed the platform view (and auxiliary resources) are lazily released (some resources are immediately released and some by platform garbage collector). A stateful widget's state is disposed when the widget is removed from the tree or when it is moved within the tree. If the stateful widget has a key and it's only moved relative to its siblings, or it has a GlobalKey and it's moved within the tree, it will not be disposed.
Construction of AppKitViews is done asynchronously, before the underlying NSView is ready this widget paints nothing while maintaining the same layout constraints.

Properties
- creationParams → dynamic
-
Passed as the
argumentsargument of -[FlutterPlatformViewFactory createWithFrame:viewIdentifier:arguments:]finalinherited - creationParamsCodec → MessageCodec?
-
The codec used to encode
creationParamsbefore sending it to the platform side. It should match the codec returned by -[FlutterPlatformViewFactory createArgsCodec:]finalinherited -
gestureRecognizers
→ Set<
Factory< ?OneSequenceGestureRecognizer> > -
Which gestures should be forwarded to the UIKit view.
finalinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- hitTestBehavior → PlatformViewHitTestBehavior
-
How this widget should behave during hit testing.
finalinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- layoutDirection → TextDirection?
-
The text direction to use for the embedded view.
finalinherited
- onPlatformViewCreated → PlatformViewCreatedCallback?
-
Callback to invoke after the platform view has been created.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- viewType → String
-
The unique identifier for iOS view type to be embedded by this widget.
