make a sample project to get sharepreference update on Android via flow (and also liveData and observable) https://github.com/Jintin/PreferencesExtension usage is like:

val preferenceLiveData = preference.liveData<String>(MY_KEY)
preferenceLiveData.observe(this) {
    // get update here
}
val observable = preference.observable<String>(MY_KEY)
observable.subscribe {
    // get update here
}
val flow = preference.flow<String>(MY_KEY)
flow.collect {
    // get update here
}

hope you guys will like it. thanks
