Warning: SDK processing. This version only understands SDK XML versions up to 3 but an SDK XML file of version 4 was encountered. This can happen if you use versions of Android Studio and the command-line tools that were released at different times.
Font asset "CupertinoIcons.ttf" was tree-shaken, reducing it from 257628 to 988 bytes (99.6% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when building your app.
