In this series, we will learn more about different list methods in #Dart and see how we can use them in #Flutter. In this episode, we have a closer look at the #reduce method in different list types in Dart. Additionally, we will see how we can use this method to calculate the total expenses in a flutter application and show it in a DataTable. Also, we will calculate the rest budget with the fold method in our flutter application.
