Methods

addItem(E item, {bool recalculatePosition = true, bool centerGraph = false}) → void
Adds a single item to the chart If an item with the same ID already exists, it will be replaced recalculatePosition determines if the position is to be recalculated directly after adding you might want to add an item but not recalculate the position immediately centerGraph wether to center the chart after adding the item - if recalculatePosition is true
addItems(List<E> items, {bool recalculatePosition = true, bool centerGraph = false}) → void
Adds multiple items to the chart Items with existing IDs will replace the old ones
calculatePosition({bool center = true}) → void
centerNode(String nodeId, {double? scale, bool animate = true, Duration duration = const Duration(milliseconds: 300), Curve curve = Curves.easeInOut}) → Future<void>
Centers a specific node in the view
changeNodeIndex(Node<E> node, int index) → void
clearItems({bool recalculatePosition = true, bool centerGraph = false}) → void
Removes all items from the chart
exportAsImage() → Future<Uint8List?>
exportAsPdf() → Future<Document?>
getOverlapping(Node<E> node) → List<Node<E>>
getSize() → Size
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
replaceAll(List<E> items, {bool recalculatePosition = true, bool centerGraph = false}) → void
Replaces all items in the chart with new items This is more efficient than clearing and adding items separately
setViewerController(CustomInteractiveViewerController controller) → void
Sets the interactive viewer controller for node centering
switchOrientation({GraphOrientation? orientation, bool center = true}) → void
Switch the orientation of the chart
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
