Dart Collections: List Types

Dart, a programming language, provides a handy tool called a "List" for managing collections of items. It's like a dynamic array that can hold a bunch of things. Let's dive into two types of Lists: Fixed Lists and Growable Lists.

1. List: Your Collection Buddy

Imagine a List as a container to store various items. It could be a list of numbers, words, or anything you want. It helps you keep things organized, just like a shopping list or a to-do list.

List<int> numbers = [1, 2, 3, 4, 5];
List<String> words = ['apple', 'banana', 'cherry'];

Here, we have a list of numbers and a list of words.

2. Fixed Lists: Set in Stone

A Fixed List is like a set plan. Once you create it, you decide how many items it will hold, and you can't change that number.

List<int> fixedList = List<int>.filled(3, 0);

In this example, we've created a fixed list with three slots, initially filled with zeros. You can't add or remove slots afterward.

3. Growable Lists: Flexibility at Its Finest

Growable Lists are more like an expandable backpack. You can start with a few items and add more whenever you want.

List<String> growableList = [];
growableList.add('carrot');
growableList.add('broccoli');
growableList.add('spinach');

Here, we begin with an empty list and gradually add vegetables to it. Growable Lists allow you to adjust the size as needed.

In a nutshell, Lists in Dart help you manage your data. Fixed Lists are like a set plan – once made, they stick to it. Growable Lists, on the other hand, give you flexibility – you can add or remove items whenever you please.

So, whether you're dealing with a fixed plan or embracing flexibility, Dart's Lists have got you covered!
