title: Flutter: ios OK, android crashing on startup without error
body: <p>I'm fairly confident this has something to do with the package name or firebase, but I've tried everything I could find on this issue in existing questions. I have triple-checked that:</p>
  
  <ul>
  <li>The package name is the same in MainActivity.kt, app/build.gradle, and AndroidManifest.xml</li>
  <li>The path to the Kotlin file is updated to android/app/main/kotlin/com/takaomatt/together (my package name is com.takaomatt.together)</li>
  <li>Restarted emulators multiple times, deleting and recreating in AVD manager in Android Studio. </li>
  <li>Deleted cache/memory &amp; uninstalled apps on emulators multiple times. </li>
  <li>Running <code>flutter clean</code> multiple times. </li>
  </ul>
  
  <p>I can't find anything else to try.</p>
  
  <p>I get the same behavior for Pixel 2 and Pixel 2 XL emulators. All ios emulators are working totally fine. </p>
  
  <p>The app flashes white briefly on startup before crashing. Here are the tail of the logs by running <code>flutter run -v</code>, it just hangs on the last output forever. </p>
