how to listen to changes instead of interval

[AliEasy]

Hi I am building an app with purpose of getting call history even in background and I want to trigger the service only when phone is making a call (with the help of https://pub.dev/packages/phone_state ) So in my case onEvent getting called by an interval is useless

How can I manage to do that?

If you want to call onEvent only once, set isOnceEvent in ForegroundTaskOptions to true.
