Collections in Dart (Part 03) - Flutter Course for Beginners #10

In this video, we continue our journey of Collections in Dart and go even deeper into more practical and real-world concepts. In Part 03, you will learn how null values work in Dart collections and how to handle them safely in your code. We will also cover iterating over Maps, so you understand how to loop through keys, values, and entries in a clean and readable way. After that, we’ll explore Nested Collections, where collections exist inside other collections, something you will see very often in real Flutter apps and APIs.

Along with that, you’ll learn about collection-if and collection-for, which help you create dynamic lists, sets, and maps based on conditions and loops. Finally, we’ll cover spread operators, so you can easily combine multiple collections and write more clean and efficient Dart code.
