✐ Examples

1 Checking if a list of integers is not empty

In this example,

  1. We create a list of integers named numbers.
  2. We use the isNotEmpty property to check if the list has elements.
  3. We then print the result to standard output.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3];
  bool hasElements = numbers.isNotEmpty;
  print('Has Elements: $hasElements'); // Prints: Has Elements: true
}

Output

Has Elements: true

2 Checking if a list of strings is empty

In this example,

  1. We create an empty list of strings named names.
  2. We use the isNotEmpty property to check if the list has elements.
  3. We then print the result to standard output.

Dart Program

void main() {
  List<String> names = [];
  bool hasNames = names.isNotEmpty;
  print('Has Names: $hasNames'); // Prints: Has Names: false
}

Output

Has Names: false
