obfuscation: flutter/dart code obfuscation support with crash log readability as normal

[JigneshWorld]

Please describe your new feature request

I would like to explore this code obfuscation support with Raygun Crash Reporting.
https://docs.flutter.dev/deployment/obfuscate

I found this document for Android but not much on the dart/flutter side.

https://raygun.com/documentation/language-guides/android/crash-reporting/proguard/
https://raygun.com/documentation/language-guides/flutter/crash-reporting/installation/

Would you please help to understand does it is currently supported or requires some work on the platform/SDK side to support this?

If it's supported currently - would you please help to navigate towards the helpful resources?

Hi Jignesh!

I understand what you mean, Raygun has support for Sourcemaps for Flutter web but not for Flutter obfuscation symbol files. I'm checking with the team, and we will get back to you.

Thank you so much @miquelbeltran for this confirmation 👍

@JigneshWorld and others.

Just wanted to let folks know that the Raygun team is looking into this.

A temporary (totally acknowledging that this far from ideal) solution for you is:

• You create an obfuscated release build of your app and get obfuscated stack traces into RG.
• To manually symbolize the stack trace, copy the obfuscated stack track from RG into a stack.txt and then run flutter symbolize -i stack.txt -d app.android-arm64.symbols

You'll need to replace the symbols file with the one that matches the app version of your release and uses the correct architecture. On Android that will in most cases be arm64 though, but you can't fully rely on that heuristic.

The Readme has been updated with instructions to deobfuscate stack-traces from Raygun.

Note that the architecture is listed in the stack-trace itself.

Thank you so much for these notes @TheRealAgentK @miquelbeltran 👍
