Methods

computeSelection({required NodePosition base, required NodePosition extent}) → NodeSelection
Returns a node-specific representation of a selection from base to extent.
containsPosition(Object position) → bool
Returns true if this DocumentNode contains the given position, or false if the position doesn't sit within this node, or if the position type doesn't apply to this DocumentNode.
copyAndReplaceMetadata(Map<String, dynamic> newMetadata) → DocumentNode
Returns a copy of this DocumentNode, replacing its existing metadata with newMetadata.
copyContent(NodeSelection 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.
copyMetadata() → Map<String, dynamic>
Returns a copy of this node's metadata.
copyWithAddedMetadata(Map<String, dynamic> newProperties) → DocumentNode
Returns a copy of this DocumentNode with newProperties added to the node's metadata.
getAffinityBetween({required NodePosition base, required NodePosition extent}) → TextAffinity

Available on DocumentNode, provided by the InspectNodeAffinity extension

Returns the affinity direction implied by the given base and extent.
getMetadataValue(String key) → dynamic
Returns this node's metadata value for the given key.
hasEquivalentContent(DocumentNode other) → bool
Returns true if the other node is the same type as this node, and contains the same content.
hasMetadataValue(String key) → bool
Returns true if this node has a non-null metadata value for the given metadata key, and returns false, otherwise.
initAddToMetadata(Map<String, dynamic> addedMetadata) → void
Adds addedMetadata to this nodes metadata.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
selectDownstreamPosition(NodePosition position1, NodePosition position2) → NodePosition
Inspects position1 and position2 and returns the one that's positioned further downstream in this DocumentNode.
selectUpstreamPosition(NodePosition position1, NodePosition position2) → NodePosition
Inspects position1 and position2 and returns the one that's positioned further upstream in this DocumentNode.
toString() → String
