In this post, I will share you how to create random numbers (integer and double) using ‘dart:math’ library.

import 'dart:math';

void main() {
  createRandomIntegers();
  print('-----------');
  createRandomDoubles();
}

/// Create and print random integers
void createRandomIntegers() {
  final random = Random();
  for (var i = 0; i < 5; i++) {
    print(random.nextInt(1000));
  }
}

/// Create and print random doubles
void createRandomDoubles() {
  final random = Random();
  for (var i = 0; i < 5; i++) {
    print(random.nextDouble());
  }
}

Output
