Pass state from child to parent component in React Native

My app has a settings screen (child component) where you can change information about yourself and I'm trying to get that to render on my app's profile screen (parent component). So the profile screen displays your info and if you want to change any info you do it in settings. Right now any changes I make in the settings screen show up in Firebase but if I go back to the profile screen the changes in settings don't render. Of course if I close the app and reload it the changes will be there because the changes in settings are registering to firebase; however, the state is not passing up from the child component to the parent. Does anyone have any advice on how to pass state from the settings (child) component up to the profile (parent) component?
