Flutter app setup (proxy & TLS)

Flutter often doesn’t respect the system proxy and certificates.

• Copy the app from /data/app/XXXXX using adb pull /data/app/XXXXX
• If the APKs are split, merge them
  • You can use mergeapks.py or apktool directly (see unpack_apk and pack_apk methods in the python script)
  • python3 mergeapks.py base.apk split_config.en.apk split_config.x86_64.apk split_config.xxhdpi.apk
• Run reFlutter on the APK containing libflutter.so
  • docker run --rm -it -v ${PWD}:/myfiles python:3.12 /bin/bash
  • pip3 install pipx && pipx install reflutter
  • /root/.local/bin/reflutter /myfiles/base.apk
• Sign using uber-apk-signer
• Install the new signed APK using adb install your.apk
