Fetch user data from Firebase database

hi,
i’m planning to fetch the data written into Firebase Realtime Database earlier (during new user registration) and pass to user profile page, after user succesfully login into app.


above is the process of writing an empty user data plus registered user email address. this one no problem.


the above is the web.gottext blocks for signup, login and user data.
here i’m not sure where gone wrong with my blocks.


while this one was successfully written user data into Firebase, and the red lines are the Firebase Authentication User UID.


lastly, in the user profile page i couldn’t fetch the data from Firebase database even the least user email address.

Can anyone here please guide me how I can fix the blocks in order to get the data correctly?
Thank you very much.

Search tutorials on youtube, you will definitely find something better or use firebase database component.

Why not use the inbuilt Firebase Database component?
