title: Dart : Printing integer along with string
body: <p>Consider the below code. </p>
  
  <pre><code>void main() {
    int num = 5;
    print('The number is ' + num);
  }
  </code></pre>
  
  <p>When I try to print the value for the variable num, I get the exception : <code>The argument type 'int' can't be assigned to the parameter type 'String'</code>.</p>
  
  <p>How do I go about in printing num?</p>
