initSchedulerBindingSignals function

void initSchedulerBindingSignals([ SchedulerBinding? binding ])

Call this method in main to setup the signals to react to the SchedulerBinding instance

void main() {
  ...
  initSchedulerBindingSignals();
  runApp(...);
}

Then in your application you can react to the timings, onFrame and onScheduleFrame signals. This is useful for driving animation outside of widgets.

effect(() {
  print('on persistent frame: $onPersistentFrameSignal');
});

effect(() {
  print('on schedule frame: $onScheduleFrameSignal');
});

effect(() {
  print('on timings: $timingsSignal');
});

Implementation

void initSchedulerBindingSignals([SchedulerBinding? binding]) {
  if (_setup) return;
  _setup = true;

  final schedulerBinding = binding ?? SchedulerBinding.instance;

  schedulerBinding
    ..addPersistentFrameCallback(onPersistentFrameSignal.set)
    ..addTimingsCallback(timingsSignal.set)
    ..scheduleFrameCallback(onScheduleFrameSignal.set, rescheduling: false);
}
