FIrebase collection duplicating list

I create an expense collection in firebase but when I access it in other screen using provider every time I add new item It duplicate the previous item as I continue inserting items it duplicate them?

final summaryDataExpense = Provider.of<ExpensesData>(context).expenseList;
final filterByYearExpense = summaryDataExpense
    .where((element) =>
        DateTime.parse(element['itemDate']).year == currentYear)
    .toList();

var totalExpenses = filterByYearExpense.map((e) => e['itemPrice']).toList();

totalExpenses return wrong length of the items existed

You need to replace type of expenseList from List to Set.

Set will take care of the duplicates.
