what is the difference between AsyncStorage and OnSaveInstanceState android

I am looking for a way to save state between screen transitions and i found OnSaveInstanceState using native Android and AsyncStorage using React Native and im generally wondering what the difference is and the pros and cons to both

OnSaveInstanceState-https://docs.microsoft.com/en-us/dotnet/api/android.app.activity.onsaveinstancestate?view=xamarin-android-sdk-9

AsyncStorage-https://reactnative.dev/docs/asyncstorage
