✐ Examples

1 Get hash code of a string

In this example,

  1. We create a string 'Hello'.
  2. We then use the hashCode property to get its hash code.
  3. We print the hash code to standard output.

Dart Program

void main() {
  int hashCodeValue = 'Hello'.hashCode;
  print(hashCodeValue);
}

Output

180399535

2 Get hash code of an integer

In this example,

  1. We create an integer 123.
  2. We then use the hashCode property to get its hash code.
  3. We print the hash code to standard output.

Dart Program

void main() {
  int hashCodeValue = 123.hashCode;
  print(hashCodeValue);
}

Output

123

3 Get hash code of a boolean

In this example,

  1. We create a boolean true.
  2. We then use the hashCode property to get its hash code.
  3. We print the hash code to standard output.

Dart Program

void main() {
  int hashCodeValue = true.hashCode;
  print(hashCodeValue);
}

Output

519018
