Fixed object not iterable error

[Yash621]

While running the app we are getting object not iterable error due to firebase versioning and lack of appId and measurementId in config object as it is necessary to add appId for firebase versions >7.2.0

This PR is for fixing that issue.

@Yash621 this one also

@Kanha-13 your PR was not solving the issue, as the main issue was in the versioning of firebase and moreover you removed this code block
export const f = firebase; export const database = firebase.database(); export const auth = firebase.auth(); export const storage = firebase.storage(); export const MAP_API = MAP_API_KEY;

which will break the peer dependencies in the whole app and will cause the app to just break down so I just raised a new PR for a more sophisticated and tested fix for the issue.

@Yash621 have you tried ./gradlew clean build , because I resolved this bug with my change and it worked for me

[Yash621]

@Kanha-13 ya the reason for that is in other files they are importing from config.js and you have removed the peer dependencies in config.example.js due to which the app is not accessing those variables but when the app will be running in production we will be renaming config.exapmle.js to config.js and hence the peer dependencies will break at that time.
