✐ Examples

1 Convert to string

In this example,

  1. We create an integer variable num with the value 123.
  2. We use the toString() method to convert it to a string.
  3. We then print the result to standard output.

Dart Program

void main() {
  int num = 123;
  String numString = num.toString();
  print('String representation of $num: $numString');
}

Output

String representation of 123: 123

2 Convert negative number to string

In this example,

  1. We create an integer variable negativeNum with the value -456.
  2. We use the toString() method to convert it to a string.
  3. We then print the result to standard output.

Dart Program

void main() {
  int negativeNum = -456;
  String negativeString = negativeNum.toString();
  print('String representation of $negativeNum: $negativeString');
}

Output

String representation of -456: -456

3 Convert zero to string

In this example,

  1. We create an integer variable zero with the value 0.
  2. We use the toString() method to convert it to a string.
