The stack cannot be correctly deobfuscation

[JDongKhan]

Hello, I am a Flutter developer and I will be preparing to use Sentry to collect user crash reports. During the testing process, I found that the Flutter code was not properly deobfuscation, and I also uploaded the symbol file according to the Sentry Dart plugin document. Did I do something wrong with this?

build app

 flutter build ios --obfuscate --split-debug-info=build

upload symbol files

 flutter packages pub run sentry_dart_plugin

configure

  upload_debug_symbols: true
  upload_source_maps: true
  upload_sources: false
  project: flutter_test
  org: tc-tc
  url:  https://sentry.io
  commits: auto
  ignore_missing: true
  wait_for_processing: true
  log_level: info

I found that app.ios-arm64.symbols symbols file was not uploaded to the sentry.

Hi which version of the plugin and flutter SDK are you using?

[JDongKhan]

The latest version

  sentry: ^8.1.0
  sentry_dart_plugin: ^2.0.0

[buenaflor]

@JDongKhan thanks, can you try the plugin 1.7.1? It might be an issue with 2.0.0

[JDongKhan]

It still exists.

 flutter packages pub run sentry_dart_plugin

[buenaflor]

Could you share more about your set up? is this problem only on iOS ?

[JDongKhan]

None of it works. This is my example. https://github.com/JDongKhan/flutter_sentry_demo

[buenaflor]

can you confirm that the debug symbols have been uploaded to sentry?

[JDongKhan]

It exists for android, but not work.

for ios, the app.ios-arm64 file not uploaded.

[denrase]

@JDongKhan Looking through the sample, there were several configuration issues.

• You need to use SentryFlutter.init instead of Sentry.init
• You need to provide sentry with the app runner
• You don't need to call WidgetsFlutterBinding.ensureInitialized(); in your main app
• You don't need a custom FlutterError.onError, sentry is handling this automatically for you
• You don't need to manually set the options.release, this format is used per default
• You don't need to provide the url param in the plugin config with sentry.io, this is the default

After fixing those I could capture a sample exception and see it with stacktrace on sentry.io:

Check out the documentation on how to further config Sentry: https://docs.sentry.io/platforms/flutter/

[alanalanlu]

@denrase is it possible to do this for sentry-dart and not sentry-flutter? I cannot use sentry-flutter for app size limitations

[buenaflor]

@alanalanlu you mean only using sentry-dart (e.g Sentry.init instead of SentryFlutter.init) in flutter applications?

[denrase]

@alanalanlu @buenaflor How much overhead does sentry-flutter add compared to sentry-dart in your case?

[alanalanlu]

@denrase sentr-flutter is 2-3mb while sentry-dart is ~250kb

[alanalanlu]

@ buenaflor yes Sentry.init and not SentryFlutter.init

[buenaflor]

@alanalanlu we have released sentry-dart/flutter8.9.0 which allows you to have stacktrace symbolication with only using Sentry.init on iOS, macOS and Android. Please try it out.
