Source context not applied to .dart stack traces

[rodolfoBee]

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

1. Install the Flutter SDK in a Flutter app
2. Upload the .dart source code to Sentry
3. Send a test event to Sentry

Expected Result

The stack trace has source code context added based on the upload files.

Actual Result

Source context is not applied to the event.

The code is not minified and build using ShoreBird.
The stack trace abs_paths is: app:///http/skydart_roster_update.dart:109:7

The uploaded file to the event's release is: ~/http/skydart_roster_update.dart

Files are uploaded using sentry dart plugin:

sentry_dart_plugin: ^2.4.0
sentry:
  project: [redacted]
  org: [redacted]
  auth_token: [redacted]
  upload_source_maps: true
  upload_sources: true

This issue seems to be limited to .dart stack traces. The same process was done with a .js stack trace as test and the uploaded source context was applied to the event.

The issue was originally reported on this internal ticket.

thanks, will have a look 👍

@denrase we should check if source context works in Flutter web on non-minified builds

Hi,

I tried changing the event absPath and package:

absPath was changed to all possible values (Flutter package name, iOS package name, Android package name, app://, app:/, ~, "")

nothing worked, then I tried changing package to match the uploaded artifacts, still nothing works!

is there a way I can view the uploaded sources so I can modify the event sent to match the ones in Sentry so the system can match them properly until you fix the issue in the SDK?

Here is my final code:

// Add a prefix to the stack trace
      options.beforeSend = (event, hint) async {
        final exceptions = event.exceptions?.map((exception) {
          final stackTrace = exception.stackTrace;
          if (stackTrace != null) {
            final frames = stackTrace.frames.map((frame) {
              final modifiedAbsPath = frame.absPath?.replaceFirst(
                "package:sky_crews",
                Platform.isIOS
                    ? "[redacted]"
                    : "[redacted]",
              );
              final modifiedPackage = frame.package?.replaceFirst(
                "sky_crew",
                Platform.isIOS
                    ? "[redacted]"
                    : "[redacted]",
              );

              return frame.copyWith(
                absPath: modifiedAbsPath,
                package: modifiedPackage,
              );
            }).toList();
            // Remove frames that has function as "exceptionLog" && fileName as "logger.dart"
            // as this is the logger function and we don't need it in the stack trace
            frames.removeWhere((frame) =>
                frame.function == "exceptionLog" &&
                frame.fileName == "logger.dart");
            return exception.copyWith(
              stackTrace: SentryStackTrace(frames: frames),
            );
          }
          return exception;
        }).toList();
        return event.copyWith(exceptions: exceptions ?? []);
      };

Thanks.

@buenaflor
I created a simple flutter web project and trigger some errors to my project.

I got a stack trace similar to the one from the affected user:

"abs_path": "http://localhost:49275/main.dart",

After that, I uploaded the file to my project/release: https://dev-curumas.sentry.io/settings/projects/flutter/source-maps/sentrytest%401.0.0%2B1/

New test events do not contain the source context: https://dev-curumas.sentry.io/issues/6285810522/events/95e91fafb6ec46b18da4ec3b1a23d86a/

I did not minify my code. From the quick internal chat it might be a result of the app not using split-debug-info, were you able to confirm this is the root cause?

@rodolfoBee just to be clear, I tried building with split-debug-info as well.. It didn't help!

Would you mind trying out the sentry-dart-plugin 2.1.0? We've done some changes to uploading dart file, not sure if that's related
