Node class final

Node represents a node in the document tree.

It contains three parts:

  • type: The type of the node to determine which block component to render it.
  • data: The data of the node to determine how to render it.
  • children: The children of the node.

Json format:

{
  'type': String,
  'data': Map<String, Object>
  'children': List<Node>,
}

list → LinkedList<Node>?
The linked list containing this element.

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
checkDocumentIntegrity() → void
check the integrity of the document (for DEBUG only)
childAtIndexOrNull(int index) → Node?
Grabs the Node from this Nodes children at a given index, if the index exists.
childAtPath(Path path) → Node?
copyWith({String? type, Iterable<Node>? children, Attributes? attributes}) → Node
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
insert(Node entry, {int? index}) → void
Inserts a Node at a given index
insertAfter(Node entry) → void
Insert an element after this element in this element's linked list.
override
insertBefore(Node entry) → void
Insert an element before this element in this element's linked list.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify() → void
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
toJson() → Map<String, Object>
toString() → String
A string representation of this object.
override
Unlink the element from its linked list.
override
updateAttributes(Attributes attributes) → void
Update the attributes of the node.

Operators

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