title: Flutter - Drawer menu behind WebViewScaffold
body: <p>i have class stateLessWidget, where i would like:</p>
  
  <p>1) Load a web page with a URL (it works well)
  2) Use a Drawer Menu (it works well)</p>
  
  <p><strong>THE ISSUE:</strong> My drawer menu is behind the view :( . </p>
  
  <p>Maybe because the WebviewScaffold load later drawer menu ?</p>
  
  <p>Thank you guys! </p>
