How to check if a Firebase App is already initialized on Android
Solution 1:
On firebase web, you check if already initialized with:
if (firebase.apps.length === 0) {
firebase.initializeApp({});
}
Solution 2:
In v9, Firebase has been modularized for better tree shaking. So we can no longer import entire app and check the apps property AFAIK. The below approach can be used instead.
import { initializeApp, getApps, getApp } from "firebase/app";
getApps().length === 0 ? initializeApp(firebaseConfig) : getApp();
