Is there a way to upload flutter's obfuscation mappings to Firebase Crashlytics

Question

My flutter app uses obfuscation for builds and creates symbols. The crash stacktraces are appearing obfuscated in the Firebase Crashlytics console. I know that we can use "flutter symbolize -i command" to deobfuscate a stacktrace, but is there a way to upload this symbols to Firebase Crashlytics console?

Answer 1

Based on this document, if your Flutter project uses the --split-debug-info flag (and, optionally, the --obfuscate flag), you need to use the Firebase CLI (v.11.9.0+) to upload Android symbols.

From the root directory of your Flutter project, run the following command:

firebase crashlytics:symbols:upload --app=APP_ID PATH/TO/symbols

The PATH/TO/symbols directory is the same directory that you pass to the --split-debug-info flag when building the application.

Also, you can find the app ID in the firebase_options.dart file.
