title: in Dart, is there a `parse` for `bool` as there is for `int`?
body: <p>in Dart, there's a convenient way to convert a String to an int:</p>
  
  
  
  <pre class="lang-dart prettyprint-override"><code>int i = int.parse('123');
  </code></pre>
  
  <p>is there something similar for converting bools?</p>
  
  <pre class="lang-dart prettyprint-override"><code>bool b = bool.parse('true');
  </code></pre>
