no setterinherited
endPosition → TextNodePosition
Returns the NodePosition that corresponds to the end of the content in this node.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
id → String

finalinherited
metadata ↔ Map<String, dynamic>

Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
computeSelection({required NodePosition base, required NodePosition extent}) → TextNodeSelection
Returns a node-specific representation of a selection from base to extent.
inherited
copyContent(dynamic selection) → String
Returns a plain-text version of the content in this node within selection, or null if the given selection does not make sense as plain-text.
inherited
copyMetadata() → Map<String, dynamic>
Returns a copy of this node's metadata.
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
getMetadataValue(String key) → dynamic
Returns this node's metadata value for the given key.
inherited
hasEquivalentContent(DocumentNode other) → bool
Returns true if the other node is the same type as this node, and contains the same content.
inherited
hasMetadataValue(String key) → bool
Returns true if this node has a non-null metadata value for the given metadata key, and returns false, otherwise.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
putMetadataValue(String key, dynamic value) → void
Sets this node's metadata value for the given key to the given value, and notifies node listeners that a change has occurred.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
selectDownstreamPosition(NodePosition position1, NodePosition position2) → NodePosition
Inspects position1 and position2 and returns the one that's positioned further downstream in this DocumentNode.
inherited
selectUpstreamPosition(NodePosition position1, NodePosition position2) → NodePosition
Inspects position1 and position2 and returns the one that's positioned further upstream in this DocumentNode.
inherited
toString() → String
A string representation of this object.

Operators

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