title: Flutter clean and flutter run doesn't rebuild the app on macOS using Visual Studio Code
body: <p>On the <strong>first compile</strong> the project is build correctly and running on both device or simulator. After that if <strong><em>I apply a change on the code</em></strong> and try the <strong>Hot Restart and rebuild</strong> the app doesn't rebuild and does not show the new modification. </p>
  
  <p>Even if I try <code>flutter clean</code> in order to clean the solution, Deleting the 'build/' path and <code>flutter run</code> after but the same issue occurs again.</p>
  
  <p>Or  <code>rm -rf build &amp;&amp; flutter run</code> </p>
  
  <p>I've updated both the Visual Studio Code and Flutter (version 1.9) in order to be up to date retry but does not make any change at all.</p>
  
  <p>I have tried to run the app from Xcode too after flutter clean and get the same issue.</p>
  
  <p>Below I'm attaching a simple print screen in order to show a simple change I've applied on a demo project on the <strong><em>title string value</em></strong> and the solution on the simulator (the same one I get on physical device too) with the code modification, and the app that doesn't rebuild.</p>
