title: Flutter - App Randomly Hangs during launch (is gc causing it?)
body: <p>My Flutter app will randomly hang during the launch process, usually on the Splash image.</p>
  <p>When checking the <code>Logging</code> feature of <code>DevTools</code> in <code>VSCode</code>, I see this:</p>
  <pre><code>gc _spawn • new space collection in 39 ms • 130.5 MB used of 185.0 MB
  gc main • new space collection in 39 ms • 130.5 MB used of 185.0 MB
  gc _spawn • idle collection in 84 ms ...
  gc main • idle collection in 84 ms ...
  ... splash images created
  gc main • idle collection in 85 ms ...
  gc main • idle collection in 128 ms ...
  flutter.frame 135.9ms ---- Splash image is on screen
  // here it hangs and it could be seconds to minutes until it 
  // picks back up &amp; I am routed to my home screen
  </code></pre>
  <p>But if it's a quick startup launch, the <code>gc</code> items are not there.</p>
  <p>What is the best way to check what is causing those &amp; how to resolve them?</p>
