These three are very important and useful for app creator, it makes us easy to call and fetch firebase data values into app. Yes possible without these three blocks, but i donot have more idea to fetch firebase when there is multiple screen.
On screen1 i initialized firebase component and yes i can store without these three block and i can even also get value from database. But when i pass to screen2 it cannot store properly. Data store without project bucket, if these three blocks were there data will store inside the project bucket.
Or i donot know to fix this? If you know please tell me.
