00:02Now that you have an idea on how to create a class, it’s time to put your new skills to the test. I want your to define an RPG Character class. The class name should be RPGCharacter. It should have a character name as string. Finally, create three instance variables for strength, dexterity and constitution. These should be of type int.

class RPGCharacter {

}

String name = '';
int strength = 0;
int dexterity = 0; 
int constitution = 0;

import 'dart:math';

void rollStats() {
    strength = Random().nextInt(16) + 3;
    dexterity = Random().nextInt(16) + 3;
    constitution = Random().nextInt(16) + 3;
}

void printStats() {
    print('$name has $strength strength, $dexterity dexterity, and $constitution constitution');
}

var fizBoz = RPGCharacter();

fizBoz.name = 'FizBoz';

fizBoz.rollStats();
fizBoz.printStats();

fizBoz.printStats();
fizBoz.rollStats();

int strength = Random().nextInt(16) + 3;
int dexterity = Random().nextInt(16) + 3; 
int constitution = Random().nextInt(16) + 3;

void main() {
  var fizBoz = RPGCharacter();
  fizBoz.name = 'FizBoz';
  fizBoz.printStats();
}
