[crashlytics]: Flavors + AAB + obfuscate builds do not produce deobfuscated Dart stack traces

[martinpelli]

Is there an existing issue for this?

• I have searched the existing issues.

Which plugins are affected?

Crashlytics

Which platforms are affected?

Android, iOS

Description

I am unable to read stack trace since I started to use flavors with Flutterfire. Read the additional notes to see what I have tried. But after hundreds of tests I have concluded the following:
Stack traces are unreadable with this specific combination: aab + flavors + obfuscation. They are readable locally when using flutter symbolize

flavors with AAB and without obfuscation works
flavors with APK works (with or without obfuscation)
without flavors with APK works (with or without obfuscation)
without flavors with AAB works (with or without obfuscation)

Reproducing the issue

flutter build aab \
    --release \
    --flavor $FLAVOR \
    --target $TARGET \
    --obfuscate \
    --split-debug-info=$ANDROID_SYMBOLS_DIR

firebase crashlytics:symbols:upload \
    --app $CRASHLYTICS_APP_ID \
    $ANDROID_SYMBOLS_DIR \
    --debug

Firebase Core version

4.5.0

Flutter Version

Additional context and comments

I have tried the following things:

Looking for builds id in .symbols and .so to upload those. I found them by running this
find build -name "libapp.so"

./build/app/outputs/symbols/android/app.android-arm.symbols

Running flutter symbolize -i error.txt -d ./build/app/outputs/symbols/android/app.android-x64.symbols
WILL GIVE ME A READABLE STACK TRACE

I also run this to make sure the build id matches the one I am uploading to crashlytics
find build \( -name "*.so" -o -name "*.symbols" \) -exec sh -c ' for f; do if file "$f" | grep -q "ELF"; then /opt/homebrew/opt/binutils/bin/greadelf -n "$f" | grep -H dbcf9df92098de8a7e98f3ee95943cd7 && echo "FOUND IN: $f" else grep -H dbcf9df92098de8a7e98f3ee95943cd7 "$f" && echo "FOUND IN: $f" fi done ' sh {} + (standard input): Build ID: dbcf9df92098de8a7e98f3ee95943cd7

No matter what I upload to sentry or crashlytcs I always have these ilegible stack trackes

I have tried:
Using the latest Flutter version 3.41.4
Using old Flutter version 3.38.7 and 3.35.6
Using the latest firebase plugins
Using old firebase plugins
Running Flutterfire config again
Running Flutterfire configure again
Running Flutterfire reconfigure again

Hi! We are experiencing the same issue. Stack traces are not being symbolicated in Firebase Crashlytics, even though the correct .symbols files are generated and uploaded successfully. Crashlytics continues to display stack traces like:
_kDartIsolateSnapshotInstructions+0x8f2517.
However, the exact same stack trace can be successfully symbolicated locally using flutter symbolize with the same .symbols file that was uploaded to Crashlytics, suggesting that:
the .symbols file is correct
the BuildId matches the crash
but Crashlytics is not applying the symbols correctly.
This problem only occurs when using flavors and building an AAB. If we run the exact same workflow but generate an APK instead, Crashlytics symbolication works perfectly.
Note that the .symbols file we use for local symbolication does not seem to match the BuildI ID reported in Crashlytics log stack trace. When inspecting the symbols file using:
file <symbols_file_path>
the Build ID reported there does not match the Build ID shown in the Crashlytics stack trace.

Hi, thanks for the detailed report and all the debugging you've done — very helpful.

We investigated this thoroughly, including the Crashlytics plugin code, the Firebase CLI crashlytics:symbols:upload command, and the firebase-crashlytics-buildtools JAR that processes symbols.

Fix

We have a fix in PR #18085 — instead of relying on the Dart VM build_id from the stack trace, the plugin now reads the ELF build ID directly from libapp.so at runtime. This ensures the ID we report to Crashlytics matches the ID that the buildtools JAR extracts from .symbols files during upload.

Could you test this with your AAB + flavor + obfuscation setup? You can depend on the fix branch by using a git dependency override:

# pubspec_overrides.yaml
dependency_overrides:
  firebase_crashlytics:
    git:
      url: https://github.com/firebase/flutterfire.git
      ref: fix/18080
      path: packages/firebase_crashlytics/firebase_crashlytics

After testing, let us know if:

1. The BuildId in Crashlytics now matches the ELF build ID from readelf -n on your .symbols files
2. Stack traces are properly symbolicated

Thanks!

Hi @Lyokone thanks for taking care of this so fast. I added the override and set firebase_core to 4.5.0 but now I am unable to receive events in crashlytcs, is like they are not being sent

[Lyokone]

Hey, we tested the fix end-to-end ourselves with a flavor app (AAB + obfuscation) and can confirm it works — stack traces are now fully deobfuscated in the Firebase console.

What was wrong

The firebase crashlytics:symbols:upload command uses the ELF build ID (from .note.gnu.build-id in libapp.so) as the key when uploading symbols. But the Flutter Crashlytics plugin was reporting the Dart VM snapshot build ID — a different identifier. For APK builds these happen to match, but for AAB builds they diverge, which is why Crashlytics couldn't match symbols to crashes.

What the fix does (PR #18085)

The plugin now reads the ELF build ID directly from libapp.so at runtime. It handles all install scenarios:

• Extracted native libs — reads from nativeLibraryDir/libapp.so
• APK installs (libs compressed inside the APK) — reads from the base APK zip
• AAB / Play Store installs (split APKs) — reads from split_config.<abi>.apk

How to test

1. Add the git dependency override to your project:

# pubspec_overrides.yaml
dependency_overrides:
  firebase_crashlytics:
    git:
      url: https://github.com/firebase/flutterfire.git
      ref: fix/18080
      path: packages/firebase_crashlytics/firebase_crashlytics

2. Build your AAB with obfuscation:

flutter build aab \
    --release \
    --flavor $FLAVOR \
    --target $TARGET \
    --obfuscate \
    --split-debug-info=symbols

3. Upload the debug symbols:

firebase crashlytics:symbols:upload \
    --app=$CRASHLYTICS_APP_ID \
    symbols

4. Install the AAB on a device (or use bundletool for emulators):

# For a physical device connected via USB:
bundletool build-apks --bundle=build/app/outputs/bundle/<flavor>Release/app-<flavor>-release.aab --output=app.apks --overwrite --connected-device
bundletool install-apks --apks=app.apks

5. Trigger a crash in your app and check the Firebase Crashlytics console — stack traces should now show actual Dart source file names and line numbers instead of raw _kDartIsolateSnapshotInstructions+0x... offsets.

Let us know how it goes!

@Lyokone testing in debug to see if all works but I get

Tried with flutter clean and flutter pub get just in case and same result

[Lyokone]

Can you give me a full GitHub repository I can clone so I can have a look at your setup?

[martinpelli]

@Lyokone What is weird to me, is that I had this in my overrides from a long time ago:

dependency_overrides:
  firebase_core_platform_interface: 5.4.1

I tried removing it and also overriding it like the firebase_crashlytics, but I get the same error I shared in the screenshot. If I execute flutter pub deps | grep crashlytics

├── firebase_crashlytics 5.0.8
   ├── firebase_crashlytics_platform_interface 3.8.18

these are my firebase deps now:

firebase_analytics: 12.0.3
firebase_auth: 6.1.1
firebase_core: 4.5.0
firebase_storage: 13.0.3
firebase_remote_config: 6.1.0
dependency_overrides:
  firebase_crashlytics:
    git:
      url: https://github.com/firebase/flutterfire.git
      ref: fix/18080
      path: packages/firebase_crashlytics/firebase_crashlytics

I can give you a repository but it will take me time to build it, right now this is in a huge production app.

[martinpelli]

@Lyokone update:

I was removing the dependency as I thought I only needed the override (but it's an override) so I put it back and I am receiving events again but unfortunately, is still not working

This is my script

fvm flutter build aab \
      --release \
      --flavor production \
      --dart-define-from-file "$ENV_FILE" \
      --obfuscate \
      --split-debug-info="$ANDROID_SYMBOLS_DIR"
    print_success "Android release completed"

    if [[ -z "$ANDROID_APP_ID" ]]; then
      print_warning "Android Firebase App ID not set; skipping Crashlytics upload"
    else
      print_status "Uploading Android symbols to Crashlytics..."
      firebase crashlytics:symbols:upload --app="$ANDROID_APP_ID" "$ANDROID_SYMBOLS_DIR" --debug
      print_success "Uploaded Android symbols to Crashlytics"
    fi

and this is the output

✓ Built build/app/outputs/bundle/productionRelease/app-production-release.aab (101.4MB)
