Flutter Riverpod listview index length

I have a listview which is using flutter_riverpod. The listview have 2 variable.
First variable is word text and second variable is length of index.

ListView.builder(
                      itemCount: ref.watch(itemsProvider).length,
                      itemBuilder: (BuildContext context, int index) {
                        return Row(
                          children: [
                            Text(ref.watch(itemsProvider)[index]),
                            Text(ref.watch(itemsProvider)[index].length),
                          ],
                        );
                      },
                    ),

I am using this listview.builder. the first text of Row is working but second text of Row is not working.
The error:

the argument type ‘int ‘ can’t be assigned to the parameter type ‘string’

Thanks for help.

>Solution :

Text widget seeks from String, Use string format

 Text("${ref.watch(itemsProvider)[index].length}"),

Also, you can use .toString()
