Variants

PushSurfacePartition

Begins a retained subtree that may be detached to another presentation surface. The marker itself has no visual effect.

Fields

id: SurfacePartitionId

PopSurfacePartition

Ends the most recent surface partition.

Rect

Fields

rect: Rect

color: Color

RRect

Fields

rrect: RRect

brush: Brush

Border

Fields

rrect: RRect

border: Border

FillPath

Fields

path: Arc<Path>

brush: Brush

fill_rule: FillRule

StrokePath

Fields

path: Arc<Path>

brush: Brush

stroke: Stroke

Image

Source is image pixels; destination is local logical geometry.

Fields

image: ImageHandle

source: Rect

destination: Rect

sampling: ImageSampling

GlyphRun

Fields

run: Arc<GlyphRun>

color: Color

PushClip

Fields

rect: Rect

PushClipRRect

Fields

rrect: RRect

PushClipOval

Fields

rect: Rect

PushClipPath

Fields

path: Arc<Path>

fill_rule: FillRule

PopClip

PushTransform

Fields

transform: Transform

PopTransform

PushOpacity

Begins an isolated retained opacity group. The compositor renders the enclosed commands into a transparent target and applies alpha once when that target is composited back into its parent.

Fields

layer: LayerId

alpha: f32

generation: u64

bounds: Rect

PopOpacity

PushBlur

Begins an isolated Gaussian-filtered subtree. The generation and bounds describe source pixels only; sigma is a compositor property.

Fields

layer: LayerId

blur: GaussianBlur

generation: u64

bounds: Rect

PushDropShadow

Begins an isolated arbitrary-subtree drop shadow. The child source is emitted once and the compositor draws the blurred alpha behind it.

Fields

layer: LayerId

shadow: DropShadowEffect

generation: u64

bounds: Rect

PushColorFilter

Begins an isolated straight-RGBA color-matrix stage.

Fields

layer: LayerId

filter: ColorFilter

generation: u64

bounds: Rect

PushBlend

Begins an isolated blend group. The source is emitted once and the compositor combines it with the destination in painter order.

Fields

layer: LayerId

mode: BlendMode

generation: u64

bounds: Rect

PushShaderMask

Begins an isolated shader-mask stage. The shader is evaluated in the mask’s logical coordinate space and blended over the child source.

Fields

layer: LayerId

shader: Brush

blend_mode: BlendMode

mask_size: Size

mask_transform: Transform

generation: u64

bounds: Rect

PushBackdropFilter

Begins a backdrop stage. The backend samples the already painted destination in bounds, filters it, and then composites the filtered pixels before the child source is painted.

Fields

layer: LayerId

blur: GaussianBlur

blend_mode: BlendMode

enabled: bool

matrix: Option<Transform>

Flutter’s ImageFilter.matrix: when set, the backdrop is transformed by it, in the stage’s coordinates, instead of blurred.

backdrop_key: Option<BackdropKey>

The backdrop this stage shares with others, if any.

generation: u64

bounds: Rect
