# startSync static method

void startSync(

1. String name, {
2. Map? arguments,
3. Flow? flow,

})

Start a synchronous operation labeled `name`. Optionally takes a Map of `arguments`. This slice may also optionally be associated with a Flow event. This operation must be finished before returning to the event queue.

## Implementation

    static void startSync(String name, {Map? arguments, Flow? flow}) {
      if (!_hasTimeline) return;
      if (!_isDartStreamEnabled()) {
        // Push a null onto the stack and return.
        _stack.add(null);
        return;
      }
      var block = new _SyncBlock._(
        name,
        _getNextTaskId(),
        arguments: arguments,
        flow: flow,
      );
      _stack.add(block);
      block._startSync();
    }
