[Feature request] Flutter Android build: Automate the upload of debug symbols zip

[orkun1675]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Steps to reproduce

This was previously brought up in https://github.com/orgs/codemagic-ci-cd/discussions/1729.

I have written the following script to automate the generation of the debug symbols archive:

rm -rf build/app/intermediates/stripped_native_libs/release/out/lib/.crashlytics \
&& cd build/app/intermediates/stripped_native_libs/release/out/lib/ && zip -r ../../../../../outputs/bundle/release/symbols.zip . && cd - \
&& mkdir -p build/$1/android_build/ \
&& cp build/app/outputs/bundle/release/symbols.zip build/$1/android_build/ \
&& echo "Upload the following debug symbols to Play Console: 'build/$1/android_build/symbols.zip'" \
|| echo "Build for Android failed!"

Is there a way for us to pass this file to Codemagic to upload it to Google Play?

If there is already an issue/bug tracking this feature request PLMK.

Thank you!
