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 taskId. This is useful if you are passing a task from one isolate to another.
