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 commande 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 diffirentt stacktrace.

So the qustion 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.
