BoxyLayerContext class

A convenient wrapper to PaintingContext, provides methods to push compositing Layers from the paint methods of BoxyDelegate.

You can obtain a layer context in a delegate through the BoxyDelegate.layers getter.

• BoxyDelegate, which has an example on how to use layers.

Methods

add({required Layer layer}) → void

Pushes a Layer to the compositing tree similar to push, but can't paint anything on top of it.

alpha({required int alpha, required VoidCallback paint, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes an OpacityLayer to the compositing tree, calling paint to paint on top of the layer.

clipPath({required Path path, required VoidCallback paint, Clip clipBehavior = Clip.antiAlias, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes a ClipPathLayer to the compositing tree, calling paint to paint on top of the layer.

clipRect({required Rect rect, required VoidCallback paint, Clip clipBehavior = Clip.antiAlias, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes a ClipRectLayer to the compositing tree, calling paint to paint on top of the layer.

clipRRect({required RRect rrect, required VoidCallback paint, Clip clipBehavior = Clip.antiAlias, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes a ClipRRectLayer to the compositing tree, calling paint to paint on top of the layer.

colorFilter({required ColorFilter colorFilter, required VoidCallback paint, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes a ColorFilterLayer to the compositing tree, calling paint to paint on top of the layer.

imageFilter({required ImageFilter imageFilter, required VoidCallback paint, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes a ImageFilterLayer to the compositing tree, calling paint to paint on top of the layer.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

offset({required Offset offset, required VoidCallback paint, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes an OffsetLayer to the compositing tree, calling paint to paint on top of the layer.

opacity({required double opacity, required VoidCallback paint, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes an OpacityLayer to the compositing tree, calling paint to paint on top of the layer.

push({required VoidCallback paint, ContainerLayer? layer, Rect? bounds, Offset offset = Offset.zero}) → void

Pushes a ContainerLayer to the current recording, calling paint to paint on top of the layer.

toString() → String

A string representation of this object.

inherited

transform({required Matrix4 transform, required VoidCallback paint, Offset offset = Offset.zero, Rect? bounds, LayerKey<Layer>? key}) → void

Pushes an TransformLayer to the compositing tree, calling paint to paint on top of the layer.

Operators
