PlatformViewLayer class - rendering library

Constructors

PlatformViewLayer({@required Rect rect, @required int viewId }): Creates a platform view layer. [...]

Properties

rect → Rect: Bounding rectangle of this layer in the global coordinate space.
final
viewId → int: The unique identifier of the UIView displayed on this layer. [...]
final
alwaysNeedsAddToScene → bool: Subclasses may override this to true to disable retained rendering.
@protected, read-only, inherited
attached → bool: Whether this node is in a tree whose root is attached to something. [...]
read-only, inherited
debugCreator ↔ dynamic: The object responsible for creating this layer. [...]
read / write, inherited
debugSubtreeNeedsAddToScene → bool: Whether any layer in the subtree needs addToScene. [...]
@visibleForTesting, read-only, inherited
depth → int: The depth of this node in the tree. [...]
read-only, inherited
hashCode → int: The hash code for this object. [...]
read-only, inherited
nextSibling → Layer: This layer's next sibling in the parent layer's child list.
read-only, inherited
owner → Object: The owner for this node (null if unattached). [...]
read-only, inherited
parent → ContainerLayer: This layer's parent in the layer tree. [...]
read-only, inherited
previousSibling → Layer: This layer's previous sibling in the parent layer's child list.
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.

Methods

addToScene(SceneBuilder builder, [ Offset layerOffset = Offset.zero ]) → EngineLayer: Override this method to upload this layer to the engine. [...]
override
find<S>(Offset regionOffset) → S: Returns the value of S that corresponds to the point described by regionOffset. [...]
override
adoptChild(covariant AbstractNode child) → void: Mark the given node as being a child of this node. [...]
inherited
attach(covariant Object owner) → void: Mark this node as attached to the given owner. [...]
@mustCallSuper, inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children. [...]
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node. [...]
inherited
debugMarkClean() → void: Mark that this layer is in sync with engine. [...]
@visibleForTesting, inherited
detach() → void: Mark this node as detached. [...]
@mustCallSuper, inherited
dropChild(covariant AbstractNode child) → void: Disconnect the given node from this node. [...]
inherited
markNeedsAddToScene() → void: Mark that this layer has changed and addToScene needs to be called.
@protected, @visibleForTesting, inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed. [...]
inherited
redepthChild(AbstractNode child) → void: Adjust the depth of the given child to be greater than this node's own depth. [...]
@protected, inherited
redepthChildren() → void: Adjust the depth of this node's children, if any. [...]
inherited
remove() → void: Removes this layer from its parent layer's child list. [...]
@mustCallSuper, inherited
replaceWith(Layer newLayer) → void: Replaces this layer with the given layer in the parent layer's child list.
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.debug }) → String: Returns a string representation of this object.
inherited
toStringDeep({String prefixLineOne: '', String prefixOtherLines, DiagnosticLevel minLevel: DiagnosticLevel.debug }) → String: Returns a string representation of this node and its descendants. [...]
inherited
toStringShallow({String joiner: ', ', DiagnosticLevel minLevel: DiagnosticLevel.debug }) → String: Returns a one-line detailed description of the object. [...]
inherited
toStringShort() → String: A brief description of this object, usually just the runtimeType and the hashCode. [...]
inherited
updateSubtreeNeedsAddToScene() → void: Traverse the layer tree and compute if any subtree needs addToScene. [...]
@protected, @visibleForTesting, inherited

Operators
