TreeNode<T extends TreeNode<T>> constructor

TreeNode<T extends TreeNode<T>>(T? parent, { int maxDeep = -1, int deep = 0, num value = 0, })

Implementation

TreeNode(this.parent, {this.maxDeep = -1, int deep = 0, num value = 0}) {
  _value = value;
  this._deep = deep;
  if (_value < 0) {
    throw FlutterError('Value must >=0');
  }
}
