- TimelineTask class
An asynchronous task on the timeline. An asynchronous task can have many
(nested) synchronous operations. Synchronous operations can live longer than
the current isolate event. To pass a TimelineTask to another isolate,
you must first call pass to get the task id and then construct a new
TimelineTask in the other isolate.
Constructors

TimelineTask()
-
Create a task. The task ID will be set by the system.
-
TimelineTask.withTaskId(int taskId)
-
Create a task with an explicit
