Node(
  1. ST type,
  2. int positionInMessage, {
  3. int expectedSymbolCount = 0,
  4. String? value,
  5. List<Node>? children,
})

Implementation

Node(this.type, this.positionInMessage,
    {this.expectedSymbolCount = 0, this.value, List<Node>? children})
    : children = children ?? <Node>[];
