title: Is it safe to save the Firebase Server Key in the Firebase Realtime Database?
body: <p>I'm making a notification submission process in android studio and I know it's not safe to leave the Firebase Cloud Messaging Server Key in the source code directly, so would it be safe if I put the key directly through the Realtime Database dashboard into a node and retrieve the key from the source code using valueSingleEventListener every time I send a notification?</p>
