**Arrays** are one of the most commonly used collections in programming. In Dart, an array is represented in the form of a **list** (i.e., an ordered collection of objects). 

Lists in Dart are further classified into fixed-length lists and growable lists.

## Fixed-length list

As the name suggests, the length of a **fixed-length list** is fixed and cannot be changed at runtime. The syntax for declaring a fixed-length list is:

```dart
var list_name = new List(size)
```
### Code
The code snippet below demonstrates how a fixed-length list can be used: 

import 'dart:convert';
void main() {
  var size = 5;
  var myList = new List(5);
  myList[0] = 'Quentin';
  myList[1] = 'Scorsese';
  myList[2] = 'Nolan';
  myList[3] = 'Anderson';
  myList[4] = 'Kubrick';
  print(myList);
}

## Growable List
The length of a growable list can be changed at runtime. 

The syntax for declaring a growable list with some predefined values is:
```dart
var list_name = [val1, val2, val3]  
```
The syntax for declaring a growable list with an initial size of zero is:
```dart  
var list_name = new List() 
```
### Code
The code snippet below demonstrates the usage of a growable list, where `add` and `remove` are used for insertion and deletion, respectively: 

import 'dart:convert';
void main() {
  var myList = [10, 20, 30];
  print("Original list: $myList");
  
  print("Adding elements to the end of the list...");
  myList.add(40);
  myList.add(50);
  print(myList);

  print("Removing '10' from the list...");
  myList.remove(10);
  print(myList);
}
