title: Add offline mode to a Flutter Web App - Service Workers/Pwas
body: <p>I need to transform a Flutter app into a PWA and I'm trying to understand if this is possible without rewriting the code in AngularDart.</p>
  
  <p>I did some research and I found out that first I need my Flutter App to become a Flutter Web App but nothing more.</p>
  
  <p>There is also a StackOverflow question that speaks about this but answers are not complete</p>
  
  <p>How to transform Flutter web app into a PWA?</p>
  
  <p>I found some PWA examples with AngularDart, JS, etc... but nothing about a Flutter PWA.</p>
  
  <p>*On the Flutter for Web homepage they mention PWAs but I didn't understand if it is already a feature or not.</p>
