Implementation

void removeNodeWhere(bool Function(NodeModel) test) {
  List<String> deletedNodes = [];
  final finalNodes = data.nodes.where((e) {
    final res = !test(e);
    if (!res) {
      deletedNodes.add(e.id);
    }
    return res;
  }).toList();
  _notifier.value = data.copyWith(
    nodes: finalNodes,
    connections: connections
        .where(
          (e) =>
              !deletedNodes.contains(e.source.nodeId) &&
              !deletedNodes.contains(e.target.nodeId),
        )
