React Native - android App Crashes Before Launch

I have recently published an app on PlayStore and I had a problem with my React Native "android Only" version as follows:

A- Status in Debug Mode:

The app would gives this error in both emulator and real android device and on a different IP other than my localhost as described in my /etc/hosts:

// Objects are not valid as a React child (found: object with keys {$$typeof, type, key, ref, props, _owner})

It would only open if I: 1- Run the debugger on "http://localhost:8081/debugger-ui" 2- run "react-native run-ios" 3- Enable "Debug JS Remotely".

I was advised that this problem would disappear on production, so I launched the app and the problem as follows:

B- Problem at Production Mode

App would install perfectly and when I launch the app I get the following error:

com.facebook.react.common.JavascriptException: Objects are not valid as a React child (found: object with keys {$$typeof, type, key, ref, props, _owner}).

package.json

"dependencies": { "firebase": "^5.8.4", "prop-types": "^15.7.2", "react": "16.6.3", "react-native": "0.58.5", "react-native-gesture-handler": "^1.0.16", "react-native-vector-icons": "^6.3.0", "react-navigation": "^3.3.0" },

Probably you are not importing firebase in the correct way. Try to import firebase this way instead of how are you doing right now:

import firebase from '@firebase/app'
import '@firebase/auth'
