title: Flutter stuck at Installing build\app\outputs\apk\app.apk
body: <p>When I run:</p>
  <pre><code>$ flutter run
  </code></pre>
  <p>I'm getting a prompt on my mobile device asking if I want to install the app on my device. I give yes, then nothing happens!</p>
  <p>It's stuck here:</p>
  <pre><code>Launching lib/main.dart on POCO F1 in debug mode...
