Methods

changeChildAtLevel(int changeLevel, DeepNavigationNode<T> newChild) → DeepNavigationNode<T>
convertNodeToString(String converter(T)) → String
createCopy({T? newValue, int? newLevel, DeepNavigationNode<T>? newChild}) → DeepNavigationNode<T>
Creates a deep copy of this DeepNavigationNode with any of the newValues if provided.
getChildAtLevel(int searchLevel) → DeepNavigationNode<T>
Returns the descendant of this node with searchLevel, which can be itself if searchLevel = level
getParentOfChild(DeepNavigationNode<T> child) → DeepNavigationNode<T>
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeLeaf() → DeepNavigationNode<T>?
removes the leaf of this child.
setChild(DeepNavigationNode<T>? newChild) → DeepNavigationNode<T>
Creates a copy of this DeepNavigationNode with the newChild.
setLeaf(DeepNavigationNode<T> newLeaf) → DeepNavigationNode<T>
Creates a copy of this DeepNavigationNode that has newLeaf set as the child of the current leaf.
toString() → String
A string representation of this object.
inherited
tryChildAtLevel(int searchLevel) → DeepNavigationNode<T>?
similar to getChildAtLevel except will return null if no descendant exists at searchLevel
