RenderTexturePainter class abstract base

A painting context passed to a Rive RenderTexture widget which will invoke the paint method as necessary to paint into the texture with a Rive renderer.

The paint method will be invoked to paint the texture.

Override the background property to set the desired background color.

Override the clear property to false to skip clearing the texture before painting.

Optionally override paintCanvas to use Flutter's native renderer to draw into the widget's RenderBox on top of Rive's texture.

The textureChanged method will be invoked when the texture is created.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
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
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
paint(RenderTexture texture, double devicePixelRatio, Size size, double elapsedSeconds) → bool
paintCanvas(Canvas canvas, Offset offset, Size size) → void
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
textureChanged() → void
toString() → String
A string representation of this object.
