Maybe there's also a problem with the icon? If you would like to see it, you can find it here: https://github.com/Myzel394/locus/blob/master/assets/launcher-icon-android.png

Okay I added the icon manually now. Here's what you need to do:

1. Read https://developer.android.com/develop/ui/views/launch/icon_design_adaptive, this contains basically everything you need to know about monochrome icons
2. Create your icon based on the doc. You need a ratio of 72x72 for your icon and a background size of 108x108.
3. Rename your file to ic_launcher_monochrome
4. Go to https://www.appicon.co/#image-sets, make sure you are on "Image Sets" and upload your file
5. You only need "Android" to be checked
6. Download & extract your icons
7. Open the extracted folder, then open android, you should see folders like drawable-hdpi, drawable-mdpi etc.
8. Copy all folders into your Flutter project under android/app/src/main/res - the res folder should already contain the same folders (drawable-hdpi, drawable-mdpi etc.), if not, you are probably in the wrong folder
9. Open android/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml
10. Add <monochrome android:drawable="@drawable/ic_launcher_monochrome"/> just before the closing tag of <adaptive-icon>

Your ic_launcher.xml should look something like this:

<?xml version="1.0" encoding="utf-8"?>
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
  <background android:drawable="@color/ic_launcher_background"/>
  <foreground android:drawable="@drawable/ic_launcher_foreground"/>
  <monochrome android:drawable="@drawable/ic_launcher_monochrome"/>
</adaptive-icon>
