Properties

artboard Artboard?
The artboard this component belongs to.
read-only, inherited
canBeOrphaned bool
Override to true if you want some object inheriting from Component to not have a parent. Most objects will validate that they have a parent during the onAdded callback otherwise they are considered invalid and are culled from core.

endX double
Change the _endX field value. endXChanged will be invoked only if the field's value has changed.

endY double
Change the _endY field value. endYChanged will be invoked only if the field's value has changed.

gradientStops List<GradientStop>
Stored list of core gradient stops are in the hierarchy as children of this container.

hashCode int
The hash code for this object. [...]

id int

name String
Non-unique identifier, used to give friendly names to elements in the hierarchy. Runtimes provide an API for finding components by this name.

Change the _opacity field value. opacityChanged will be invoked only if the field's value has changed.

runtimeType Type
A representation of the runtime type of the object.

shapePaintContainer → ShapePaintContainer?
The container is usually either a Shape or an Artboard, basically any of the various ContainerComponents that can contain Fills or Strokes.

Methods

addDependent(Component dependent, {Component? via}) bool
Mark dependent as a component which must update after this. Provide via as the Component registering the dependency when it is not dependent itself. At edit time this allows the editor to rebuild both dependent and via when dependent has its dependencies cleared.
inherited
addDirt(int value, {bool recurse = false}) bool
inherited
appendChild(Component child) → void
inherited
buildDependencies() → void
Gradients depends on their shape.
inherited
buildDrawOrder(List<Drawable> drawables, DrawRules? rules, List<DrawRules> allRules) → void
inherited
childAdded(Component child) → void
inherited
childRemoved(Component child) → void
inherited
clearDependencies() → void
inherited
clone<K extends Core<CoreContext>>() → K?
Make a duplicate of this core object, N.B. that all properties including id's are copied.
inherited
copy(covariant LinearGradientBase source) → void
Copies property values, currently doesn't trigger change callbacks. It's meant to be a helper for clone.

endXChanged(double from, double to) → void

endYChanged(double from, double to) → void

isValidParent(Component parent) bool

makeGradient(Offset start, Offset end, List<Color> colors, List<double> colorPositions) Gradient
@protected, inherited
markGradientDirty() → void
Mark the gradient as needing to be rebuilt. This is a more efficient version of markStopsDirty as it won't re-sort the stops.
inherited
markRebuildDependencies() → void
inherited
markStopsDirty() → void
Mark the gradient stops as changed. This will re-sort the stops and rebuild the necessary gradients in the next update cycle.
inherited
nameChanged(String from, String to) → void
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
onAdded() → void
inherited
onAddedDirty() → void
inherited
onDependencyRemoved(Component dependent) → void
Something we depend on has been removed. It's important to clear out any stored references to that dependency so it can be garbage collected (if necessary).
inherited
onDirty(int mask) → void
inherited
onRemoved() → void
When a component has been removed from the Core Context, we clean up any dangling references left on the parent and on any other dependent component. It's important for specialization of Component to respond to override onDependencyRemoved and clean up any further stored references to that component (for example the target of a Constraint).

@protected, inherited
parentIdChanged(int from, int to) → void
inherited
prependChild(Component child) → void
inherited
remove() → void
inherited
removeRecursive() → void
Recursive version of Component.remove. This should only be called when you know this is the only part of the branch you are removing in your operation. If your operation could remove items from the same branch multiple times, you should consider building up a list of the individual items to remove and then remove them individually to avoid calling remove multiple times on children.
inherited
resolveArtboard() bool
Find the artboard in the hierarchy.
inherited
startXChanged(double from, double to) → void
inherited
startYChanged(double from, double to) → void
inherited
syncColor() → void
inherited
toString() String
A string representation of this object. [...]
inherited
update(int dirt) → void
inherited
userDataChanged(dynamic from, dynamic to) → void
inherited
validate() bool
inherited
visitAncestor(Component ancestor) → void
Called whenever we're resolving the artboard, we piggy back on that process to visit ancestors in the tree. This is a good opportunity to check if we have an ancestor of a specific type. For example, a Path needs to know which Shape it's within.
