Hello, good morning everyone,
Before they say if I’ve done my homework ?! Yes! I already did it. I’ve searched the internet, other sources, here in the community, some gave me some suggestions has put into practice, but without result.
I have this screen, a viewer lists you, where pulls from the firebase database, some data from the database tag list.
But it turns out that when I pull in the list viewer a tag specifies where some data was not placed in that tag, it gives me this error.
Yes it is a list.
Because when I click on a tag in my list viewer, where there aren’t some values in the list, it works. It pulls the requested information.
What you are doing wrong is you are trying to to select item of list which is not list in else condition you are first choosing sabados and bcz sabados is not list and you are trying to g take it as list
Hello, @parmarparth996
The first option is not. As for the second option, it is not to give error, because I am looking for other items in the same list and gives no error.
Bcz just imagine the value of tag A is list which contains 1,2,3 so what you are doing is you are first get the length of list and on that number you are selecting a item so basically all time item will be last which is not list
