How to check obfuscation results of flutter app?

问题

In native android development I could check whether my minifyEnabled had taken effect.

I used this script (in linux) which allows me to extract the apk and view the java files to see if my code is readable, or has been obfuscated :

#! /bin/bash
d2j=/work/installs/dex2jar-2.0
jdgui=/work/installs/jd-gui-1.4.0.jar
apk_loc=/work/projects/my_app/build/app/outputs/app-release.apk

mkdir -p /work/tmp/dex
rm -rf /work/tmp/dex/*
cd /work/tmp
cp $apk_loc ./app-release.zip
unzip app-release.zip -d dex
cd dex

chmod +x $d2j/*.sh
$d2j/d2j-dex2jar.sh classes.dex

java -jar $jdgui classes-dex2jar.jar

If I use this script on a flutter apk, I don't see any files containing anything related to my original code.

Flutter's dart code is compiled to native and embedded to flutter.so runtime, so decompiling flutter is not as easy as byte code of java/kotlin However decompiling .so file is possible. You can use the toolchains inside the android ndk to perform the type of disassembling you want to

./android-ndk-r15b/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/bin/arm-linux-androideabi-objdump -T "flutter.so | less

but this is just give you an objdump.
