TreeEntry<T extends Object> class

Used to store useful information about node in a tree.

Instances of this class are short lived, created by TreeController when traversing the tree; each traversal creates a new TreeEntry for each visited node with up to date values.

To make sure that tree views are always up to date make sure to call TreeController.rebuild to notify its listeners that the tree structure changed in some way and they should update their cached values.

Constructors

TreeEntry({required TreeEntry<T>? parent, required T node, required int index, required int level, required bool isExpanded, required bool hasChildren, bool hasNextSibling = true})
Creates a TreeEntry.

Properties

hasChildren → bool
Whether node has any child nodes.
final
hashCode → int
The hash code for this object.
no setterinherited
hasNextSibling → bool
Whether the node that owns this entry has another node after it at the same level.
no setter
index → int
The index of node in the flat tree list that originated this entry.
final
isExpanded → bool
The expansion state of node.
final
level → int
The level of the node that owns this entry on the tree. Example:
final
node → T
The tree node that originated this entry.
final
parent → TreeEntry<T>?
The direct parent of node on the tree, which was collected during traversal.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
skipIndentAndPaint → bool
Whether this entry should skip being indented.
no setter
