removeNode method

@override void removeNode(String path, { bool recurse = true, })

Removes the node specified at path.

Implementation

@override

  if (path == '/' || !path.startsWith('/')) return;
  var node = getNode(path) as SimpleNode?;

    var base = path;
    if (!base.endsWith('/')) {
      base += '/';
    }

    var baseSlashFreq = countCharacterFrequency(base, '/');

    var targets =
        nodes.keys.where((String x) {
          return x.startsWith(base) &&
              baseSlashFreq == countCharacterFrequency(x, '/');
        }).toList();

    for (var target in targets) {
      removeNode(target);
    }
  }

  var p = Path(path);
  var pnode = getNode(p.parentPath) as SimpleNode?;

  node.removed = true;

  if (pnode != null) {
    pnode.children.remove(p.name);
    pnode.onChildRemoved(p.name, node);
    pnode.updateList(p.name);
  }

  if (node.callbacks.isEmpty && !node._hasListListener) {
    nodes.remove(path);
  } else {
