onTurnStart property

@override Stream get onTurnStart

A synchronous stream that fires when the VM turn has started, which means that the inner (managed) zone has not executed any microtasks.

Note:

• Causing any turn action, e.g., spawning a Future, within this zone will cause an infinite loop.

Implementation

@override
Stream get onTurnStart {
  if (_onTurnStartController == null) {
    _onTurnStartController = StreamController.broadcast(sync: true);
  }
  return _onTurnStartController!.stream;
}
