✐ Examples

1 Check if a positive integer is even

In this example,

  1. We create an integer variable number1 with the value 10.
  2. We access its isEven property to check if it is even.
  3. We then print the result to standard output.

Dart Program

void main() {
  int number1 = 10;
  bool isEven1 = number1.isEven;
  print('$number1 is even: $isEven1');
}

Output

10 is even: true

2 Check if a positive integer is odd

In this example,

  1. We create an integer variable number2 with the value 7.
  2. We access its isEven property to check if it is even.
  3. We then print the result to standard output.

Dart Program

void main() {
  int number2 = 7;
  bool isEven2 = number2.isEven;
  print('$number2 is even: $isEven2');
}

Output

7 is even: false

3 Check if a negative integer is even

In this example,

  1. We create an integer variable negativeNumber with the value -6.
  2. We access its isEven property to check if it is even.
  3. We then print the result to standard output.

Dart Program

void main() {
  int negativeNumber = -6;
  bool isEvenNegative = negativeNumber.isEven;
  print('$negativeNumber is even: $isEvenNegative');
}

Output

-6 is even: true
