Constructors

ComponentData({String? id, Offset position = Offset.zero, Size size = const Size(80, 80), Size minSize = const Size(4, 4), String? type, dynamic data})

Represents data of a component in the model.

ComponentData.fromJson(Map<String, dynamic> json, {dynamic decodeCustomComponentData(Map<String, dynamic> json)?})

Properties

childrenIds → List<String>

List of children of this component.

final

connections → List<Connection>

Defines to which components is this components connected and what is the connectionId.

final

data → dynamic

Dynamic data for you to define your own data for this component.

final

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

Whether any listeners are currently registered.

no setter, inherited

id → String

Unique id of this component.

final

minSize → Size

Minimal size of a component.

final

parentId ↔ String?

Assigned parent to this component.

getter/setter pair

position ↔ Offset

Position on the canvas.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

addChild(String childId) → void

Sets the component's parent.

addConnection(Connection connection) → void

Adds new connection to this component.

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

getPointOnComponent(Alignment alignment) → Offset

Returns Offset position on this component from alignment.

move(Offset offset) → void

Translates the component by offset value.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyListeners() → void

Call all the registered listeners.

inherited

removeChild(String childId) → void

Removes child's id from children.

removeConnection(String connectionId) → void

Removes existing connection.

removeListener(VoidCallback listener) → void

Remove a previously registered closure from the list of closures that are notified when the object changes.

inherited

removeParent() → void

Removes parent's id from this component data.

resizeDelta(Offset deltaSize) → void

Changes the component's size by deltaSize.

setParent(String parentId) → void

Sets the component's parent.

setPosition(Offset position) → void

Sets the position of the component to position value.

setSize(Size size) → void

Sets the component's to size.

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

override

updateComponent() → void

Updates this component on the canvas.

Operators

operator ==(Object other) → bool

The equality operator.
