First login check and get tag list problem

The logins to the application I’m trying to do will be via Gmail. There will be a table in FireBase and sub-tables within it for each logged in.

  1. For this, I want to check whether the logged in person has entered the application for the first time.
  2. I want to check if there is a tag under a table in the database, but the get tag list does not work because there are no tags.
    How would you recommend a solution for my two problems.
    I’m sorry for my bad english.

Show me the blocks and firebase tag list

You can use tinyDB to store to stock whenever user click the button and yoi can set block to count the number of clicks too

Data on TinyDb will be lost when the application is deleted and reinstalled. The user will be considered as if they entered it for the first time. And his data in FireBase will be deleted. So using TinyDb is not a solution for me.

Then store in firebase with additional tag (clicks) then when screen initialize call that firebase value and if the user clicks add +1

I’ve created sample blocks for what I’m trying to do. However, because When Tag List doesn’t work, I can’t do what I want.

This block will work if your project bucket is empty
