Methods

adjust() → void

Adjust this text node by merging it with adjacent nodes if they share the same style.

override

applyAttribute(Attribute attribute) → void

inherited

applyStyle(Style value) → void

inherited

clearLengthCache() → void

override

clearOffsetCache() → void

inherited

clearStyle() → void

inherited

clone() → Node

inherited

containsOffset(int offset) → bool

Returns true if this node contains character at specified offset in the document.

inherited

cutAt(int index) → Leaf?

Cuts a leaf from index to the end of this node and returns new node in detached state (e.g. mounted returns false).

delete(int index, int? len) → void

override

format(Style? style) → void

Formats this node and optimizes it with adjacent leaf nodes if needed.

insert(int index, Object data, Style? style) → void

override

insertAfter(Node entry) → void

Insert an element after this element in this element's linked list.

inherited

insertBefore(Node entry) → void

Insert an element before this element in this element's linked list.

inherited

newInstance() → Node

abstract methods begin

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

retain(int index, int? len, Style? style) → void

override

splitAt(int index) → Leaf?

Splits this leaf node at index and returns new node. If this is the last node in its list and index equals this node's length then this method returns null as there is nothing left to split. If there is another leaf node after this one and index equals this node's length then the next leaf node is returned.

toDelta() → Delta

override

toPlainText([Iterable<EmbedBuilder>? embedBuilders, EmbedBuilder? unknownEmbedBuilder]) → String

inherited

toString() → String

A string representation of this object.

override

unlink() → void

Unlink the element from its linked list.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
