AsyncNode constructor Null safety

AsyncNode(
  1. {required AsyncJob job,
  2. required String label,
  3. String? description,
  4. int maxRetry = 1,
  5. Object? extra}
)

Implementation

AsyncNode({
  required AsyncJob job,
  required this.label,
  this.description,
  this.maxRetry = 1,
  this.extra,
}) : _job = job;
