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.


TimelineTask({TimelineTask parent })
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. [...]


hashCode int
The hash code for this object. [...]
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited


finish({Map arguments }) → void
Finish the last synchronous operation that was started. Optionally takes a Map of arguments.
instant(String name, { Map arguments }) → void
Emit an instant event for this task. Optionally takes a Map of arguments.
pass() int
Retrieve the TimelineTask's task id. Will throw an exception if the stack is not empty.
start(String name, { Map arguments }) → void
Start a synchronous operation within this task named name. Optionally takes a Map of arguments.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
toString() String
Returns a string representation of this object.


operator ==(dynamic other) bool
