title: Catch multiple specific exception types in Dart with one catch expression
body: <p>I know I can catch a specific Exception type in dart with the following:</p>
  
  <pre><code>try {
    ...
  } on SpecificException catch(e) {
    ...
  }
  </code></pre>
  
  <p>But is there a way to catch multiple specific exception types with on line instead of using multiple catch statements?</p>
