Steps to Reproduce

Setup sentry for Flutter web and record an exception in release mode with error object and stack trace.

My settings are as follows:

pubspec.yaml

sentry:
  upload_sources: true
  upload_source_maps: true
  upload_debug_symbols: true
  wait_for_processing: true
  log_level: trace
  web_build_path: build/web
  org: <org>
  project: <project>
  auth_token: <token>

main.dart

await SentryFlutter.init(
  (options) {
    options.dsn = <dsn>;
    options.tracesSampleRate = 1.0;
    options.profilesSampleRate = 1.0;
    options.release = <release>;
  },
  appRunner: () => runApp(
    SentryWidget(
      child: const MyApp(),
    ),
  ),
);

I'm then building for web and then uploading the source maps as follows:

fvm flutter build web --release --source-maps --pwa-strategy=none
fvm dart run sentry_dart_plugin

Expected Result

Stack trace on https://sentry.io should show the stack trace in dart files, not the compiled javascript files.

Actual Result

Stack traces are shown in the compiled javascript files.

@chriscarman-mp thanks for reaching out, we'll take a look. Can you share a link to the issue on sentry.io, either here or via [email protected]?

Hey @chriscarman-mp! I see you are setting release in your sentry init. The plugin is reading release and dist from your pubspec.yaml per default. Please also set a dist and make sure they are the same as in pubspec.yaml.
