TimelineTask constructor

  1. {TimelineTask? parent,
  2. String? filterKey}

Create a task. The task ID will be set by the system.

If parent is provided, the parent's task ID is provided as argument 'parentId' when start is called. In DevTools, this argument will result in this TimelineTask being linked to the parent TimelineTask.

If filterKey is provided, a property named filterKey will be inserted into the arguments of each event associated with this task. The filterKey will be set to the value of filterKey.


TimelineTask({TimelineTask? parent, String? filterKey})
    : _parent = parent,
      _filterKey = filterKey,
      _taskId = _getNextTaskId() {}
