Getting List Length

Part of the Fundamentals section of Coddy's Dart journey — lesson 51 of 94.

The length property of a list returns the number of elements it contains. This helps you know how many items are in your list.

Create a list of numbers:

List<int> scores = [85, 92, 78, 96, 88];

Get the length of the list using the length property:

int numberOfScores = scores.length;
print('Number of scores: $numberOfScores');

After executing the above code, the output will be:

Number of scores: 5

Challenge

Beginner

In this challenge, you'll practice getting the length of a list in Dart. The length property tells you how many elements are in a list.

Complete the code below to find the length of the fruits list and store it in the numberOfFruits variable.

Expected output:

The shopping list contains 5 items.

Cheat sheet

The length property returns the number of elements in a list:

List<int> scores = [85, 92, 78, 96, 88];
int numberOfScores = scores.length;
print('Number of scores: $numberOfScores'); // Output: Number of scores: 5

Try it yourself

void main() {
  // This list is already defined for you
  List<String> fruits = ['Apple', 'Banana', 'Orange', 'Grapes', 'Mango'];
  
  // TODO: Get the length of the fruits list and store it in numberOfFruits
  int numberOfFruits = 0;
  
  // This will display the result
  print('The shopping list contains $numberOfFruits items.');
}
