Possible explorations
-
[90k]Dig more into what the AppClip binary is. -
[1.6m]Build App.framework/App with split-debug-info. -
[781k]The NOTICES file is huge. Since the uncompressed size is being measured here, there might be de-duplication potential. Deduplicate NOTICES #71102 -
[1m]The 70kb ld-temp.o and the 950kb unattributed code in the Flutter.framework/Flutter / libflutter.so is suspicious.
