title: Where is `dart:uri` now?
body: <p>I want to call <code>decodeUrl(...)</code> and I was doing it as:</p>
  
  <pre><code>import "dart:uri";
  
  main() {
      decodeUrl("str");
  }
  </code></pre>
  
  <p>But now with the latest Dart-SDK, it reports:</p>
  
  <pre><code>Do not know how to load 'dart:uri'
  import 'dart:uri';
  ^
  </code></pre>
  
  <p>Seems it has been removed from the SDK. I searched a lot but still don't know where is it now. How to use the <code>decodeUrl(...)</code> with latest SDK now?</p>
