✐ Examples

1 Check equality of two strings

In this example,

We create two strings `str1` and `str2` with the same value 'Hello'. We use the `==` operator to check if they are equal.

Dart Program

void main() {
  String str1 = 'Hello';
  String str2 = 'Hello';
  bool isEqual = (str1 == str2);
  print('Is str1 equal to str2: $isEqual');
}

Output

Is str1 equal to str2: true

2 Check equality of two integers

In this example,

We create two integers `num1` and `num2` with the same value 42. We use the `==` operator to check if they are equal.

Dart Program

void main() {
  int num1 = 42;
  int num2 = 42;
  bool isEqual = (num1 == num2);
  print('Is num1 equal to num2: $isEqual');
}

Output

Is num1 equal to num2: true

3 Check equality of two lists

In this example,

We create two lists `list1` and `list2` with the same elements. We use the `==` operator to check if they are equal.

Dart Program

void main() {
  List<int> list1 = [1, 2, 3];
  List<int> list2 = [1, 2, 3];
  bool isEqual = (list1 == list2);
  print('Is list1 equal to list2: $isEqual');
}

Output

Is list1 equal to list2: true
