title: Flutter pwa app no service worker detected
body: <p>I know that <a href="https://medium.com/flutter/flutter-web-support-updates-8b14bfe6a908" rel="nofollow noreferrer">flutter supports PWA</a>, but I can't enable it in my flutter web app. <a href="https://ferraridamiano.github.io/ConverterNOW/#/" rel="nofollow noreferrer">My web app</a> meet all the <a href="https://web.dev/install-criteria/" rel="nofollow noreferrer">requirements</a> for PWA support. But both chrome and edge doesn't display the install prompt. If I inspect the page I find the following message: &quot;No matching service worker detected. You may need to reload the page, or check that the scope of the service worker for the current page encloses the scope and start URL from the manifest&quot;. I have no experience in web programming.</p>
  <p>Here's my manifest:</p>
  <pre><code>{
      &quot;name&quot;: &quot;Converter NOW&quot;,
      &quot;short_name&quot;: &quot;Converter NOW&quot;,
      &quot;start_url&quot;: &quot;.&quot;,
      &quot;display&quot;: &quot;minimal-ui&quot;,
      &quot;background_color&quot;: &quot;#0175C2&quot;,
      &quot;theme_color&quot;: &quot;#0175C2&quot;,
      &quot;description&quot;: &quot;A Unit and Currencies Converter. Converter NOW is immediate, fast and easy to use!&quot;,
      &quot;orientation&quot;: &quot;portrait-primary&quot;,
      &quot;prefer_related_applications&quot;: false,
      &quot;icons&quot;: [
          {
              &quot;src&quot;: &quot;icons/Icon-192.png&quot;,
              &quot;sizes&quot;: &quot;192x192&quot;,
              &quot;type&quot;: &quot;image/png&quot;
          },
          {
              &quot;src&quot;: &quot;icons/Icon-512.png&quot;,
              &quot;sizes&quot;: &quot;512x512&quot;,
              &quot;type&quot;: &quot;image/png&quot;
          }
      ]
  }
  
  </code></pre>
