I am trying to use this code. But, for some reason I get an error that I do not fit into the range. It's just that several elements can come from the server, so I can't use hardcode and specify values like 1,2 and so on...

Here is the error I am getting - RangeError (index): Invalid value: Only valid value is 0: 1

And here is my code -

child: Text(' name - ${catalogDrawer[index].one[index].name}'),

of course it's wrapped in ListView.builder Essence of the question. How can I use an index multiple times?

As the error said the only valid value for one is 0, and your listView items is base on catalogDrawer's length. So you can't use catalogDrawer's index on one's items. you either can use an other listView and use that index to show one's items or if you sure it only have one value use catalogDrawer[index].one.first.name.
