how to add extra list in list view.builder in flutter

Question

I want to add an extra list that shows the total number of entries in ListView.builder().

My code is below, but it is not working as index not possible to compare to length.

return Scaffold(
      appBar: AppBar(title: Text('Exp Entries'),),
      body: ListView.builder(
          itemCount: noteprovider.expenseentries.length,
          itemBuilder: (context,index){

            if(index==noteprovider.expenseentries.length)
              return Text(noteprovider.expense_total.toString());
            else
             return Text(noteprovider.expenseentries[index].title);

          }),
    );

do you mean extra Item on ListView?

You must add +1 to length on itemCount :

return Scaffold(
      appBar: AppBar(title: Text('Exp Entries'),),
      body: ListView.builder(
          itemCount: noteprovider.expenseentries.length + 1,
          itemBuilder: (context,index){

            if(index==noteprovider.expenseentries.length)
              return Text(noteprovider.expense_total.toString());
            else
             return Text(noteprovider.expenseentries[index].title);

          }),
    );
