The various phases that a SchedulerBinding goes through during SchedulerBinding.handleBeginFrame.

This is exposed by SchedulerBinding.schedulerPhase.

The values of this enum are ordered in the same order as the phases occur, so their relative index values can be compared to each other.

See also WidgetsBinding.beginFrame.

Constants

idle → SchedulerPhase

No frame is being processed. Tasks (scheduled by WidgetsBinding.scheduleTask), microtasks (scheduled by scheduleMicrotask), Timer callbacks, event handlers (e.g. from user input), and other callbacks (e.g. from Futures, Streams, and the like) may be executing.

const SchedulerPhase(0)
persistentCallbacks → SchedulerPhase

The persistent callbacks (scheduled by WidgetsBinding.addPersistentFrameCallback) are currently executing.

Typically, this is the build/layout/paint pipeline. See WidgetsBinding.beginFrame.

const SchedulerPhase(2)
postFrameCallbacks → SchedulerPhase

The post-frame callbacks (scheduled by WidgetsBinding.addPostFrameCallback) are currently executing.

Typically, these callbacks handle cleanup and scheduling of work for the next frame.

const SchedulerPhase(3)
transientCallbacks → SchedulerPhase

The transient callbacks (scheduled by WidgetsBinding.scheduleFrameCallback and WidgetsBinding.addFrameCallback) are currently executing.

Typically, these callbacks handle updating objects to new animation states.

const SchedulerPhase(1)
values → List<SchedulerPhase>

A constant List of the values in this enum, in order of their declaration.

const List<SchedulerPhase>
