Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
changePosition(Offset newPosition) → dynamic: Change element position in the dashboard
changeSize(Size newSize) → dynamic: Change element size
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
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
setBackgroundColor(Color color) → dynamic: Set background color
setBorderColor(Color color) → dynamic: Set border color
setBorderThickness(double thickness) → dynamic: Set border thickness
setElevation(double elevation) → dynamic: Set elevation
setFontFamily(String? fontFamily) → dynamic: Set text font family
setId(String id) → dynamic: Used internally to set an unique Uuid to this element
setIsResizing(bool resizing) → dynamic: When setting to true, a handler will disply at the element bottom right to let the user to resize it. When finish it will disappear.
setScale(double currentZoom, double factor) → dynamic
setText(String text) → dynamic: Set text
setTextColor(Color color) → dynamic: Set text color
setTextIsBold(bool isBold) → dynamic: Set text bold
setTextSize(double size) → dynamic: Set text size
toJson() → String
toMap() → Map<String, dynamic>
toString() → String: A string representation of this object.
override

Operators

operator ==(covariant FlowElement other) → bool: The equality operator.
