# start method

void start(

1. String name, {
2. Map? arguments,

})

Start a synchronous operation within this task named `name`. Optionally takes a Map of `arguments`.

## Implementation

    void start(String name, {Map? arguments}) {
      if (!_hasTimeline) return;
      if (!_isDartStreamEnabled()) {
        // Push a null onto the stack and return.
        _stack.add(null);
        return;
      }
      final block = _AsyncBlock._(name, _taskId);
      _stack.add(block);
      block._start({
        ...?arguments,
        if (_parent != null) 'parentId': _parent._taskId.toRadixString(16),
        if (_filterKey != null) _kFilterKey: _filterKey,
      });
    }
