How to choose the right .symbols file to deobfuscate a stacktrace from crashlytics

Question

After I release obfuscated flutter app to playstore, all the stacktrace in crashlytics dashboard are are not readable. I found this command to deobfuscate the stacktrace:

flutter symbolize -i stacktrace_obfuscated.txt -d  "$HOME"/debuginfo/app.android-arm64.symbols

The problem is, there is 3 .symbols files are generated after the build, app.android-arm64.symbols, app.android-arm.symbols, app.android-x64.symbols, and I tried to deobfuscate the stacktrace with all of them, and I got 3 readable different stacktrace.

The question is: how can I choose the right .symbols to deobfuscate the stacktrace?

Recently a new feature was included to support Flutter apps built with --split-debug-info and --obfuscate flags on Android. This could help you avoid doing this step to deobfuscate the crash reports.

See this for reference.
