I am storing data in firebase, then recover it! When looking for the data I want to show the data is not stored, but it shows me an error … I don’t know what I’m failing .. ¿Happy?
There’s no need for sarcasm. The guidelines state only English is allowed in the forum. It’s up to you to follow the guidelines, not do whatever you like then be sarcastic about it.
Because of this behaviour I will let someone else answer your question, even though it’s very obvious what the problem is.
Search the forum if you don’t want to wait as this has been answered before.
Goodbye.
¿can you give me an example?
yes of course, there it is
and this is the make a list block
