Attempt to get item number 3 of a list of length 0

Attempt to get item number 3 of a list of length 0 …

I know the topic has already been posted. But I’ve read practically all the topics and I couldn’t find a solution for my project.
I already did the “DO IT” and saw that the TAG receives the value perfectly but FIREBASE doesn’t seem to find 20220701203715 (or any other). Please can someone help me?

FIREBASE parameters are correct. Because they are the same as SCREEN3 that has the LIST VIEW that sends the TAG (20220701203715) to this SCREEN4
Any tips are very helpful

Thanks…

Thanks. the value is what comes from the LIST on the previous page. TITLE - is the ID of the BUCKET (20220701203715)


When you click on the LIST ITEM, it opens another screen and loads the value for that screen

blocks(52)
Try doing this
Split text at comma and select whatever index you want.

Unfortunately it didn’t work…

I put it in block “4”… but I believe that the problem happens in the previous block, the “3”.

Is firebase returning any value whenever you get value on block 3?

Have you set project bucket?

You say… Like this?

It’s a mystery.

I think I’ll delete the project and make it from some template. It’s very difficult to do it alone. I’m still learning.

“Click on a list item and display on another screen”.
This is my difficulty.

If anyone can explain how to do it…

Why won’t you post your aia here so someone might check it ?


While calling the tag just use the his as bucket

How to test FIREBASE? TO DO IT…
“Attempt to get item 3 number of a list of length 0”

I’m tired… I’ll look for ready-made models on the internet.

If someone can show an image of how it is done… CLICK ON AN ITEM IN THE LIST AND DISPLAY ANOTHER SCREEN WITH THE INFORMATION… Using FIREBASE,
I thank.

see , i mean like this

if you are showing the values into a listview then then
