Source Maps does not works with Flutter Web

[ghost]

Environment

Flutter SDK version

"flutterSdkVersion": "3.0.5"

sentry_dart_plugin version:

sentry_dart_plugin: ^1.0.0-beta.1

stdout: > Found 3631 release files
> Analyzing 3631 sources
> Rewriting sources
> Adding source map references
> Bundled 3631 files for upload
> Uploaded release files to Sentry
> File upload complete (processing pending on server)
> Organization: novade
> Project: novade
> Release: novade_lite@1.7.0+63
> Dist: 63

Steps to Reproduce

1. Build the project for web.
2. Setup pubspec config as following

sentry:
  upload_source_maps: true

3. Run flutter flutter packages pub run sentry_dart_plugin

Expected Result

We were using sentry-cli to upload source map previously and it also didn't work. We were asked to try this new plugin and seem it also doesn't work.

Actual Result

Source maps should setup correctly.

@chathu-novade The screenshot is about the source maps of the Dart SDK itself and not your App's code.
Do you see your App's code symbolicated? that should work OOTB.

[ghost]

This is what the stack looks like. Can not see the anything related to app code.

[ghost]

The hidden source section of the screenshot looks like the following.

source: https://domain.tld/hostedtoolcache/Flutter/3.0.5/macos/flutter/.pub-cache/hosted/pub.dartlang.org/sentry-6.9.1/lib/src/sentry_client.dart

[marandaneto]

I don't follow, the screenshot below has the symbolicated stack trace, it's not minified, what's the problem you are having? can you please update the issue description with more details?

[ghost]

@marandaneto I can not see any stack trace related my my dart code in the flutter project. It show only minified:e4b and exception but not the line of dart code.

[marandaneto]

@chathu-novade can you provide the code snippet of the Sentry SDK init?
Can you provide the full config of the sentry plugin?
Can you provide the command line you are using to build your Flutter app?
Can you provide a link to an issue on sentry.io so I can have a look?

Sentry SDK init

 await SentryFlutter.init(
      (options) {
        options
          ..environment = env.toStr()
          ..release = sentryRelease // from String.fromEnvironment('SENTRY_RELEASE')
          ..dsn = dsn;
      },
      // Init your App.
      appRunner: () => runApp(const _App()),
    );

Sentry plugin config

sentry:
  upload_source_maps: true

Flutter build command

flutter build web --dart-define=SENTRY_RELEASE=$(SENTRY_RELEASE) --dart-define=AMPLITUDE_API_KEY=$(AMPLITUDE_API_KEY) -t lib/web/main.staging.dart --web-renderer canvaskit --source-maps --dart-define=BROWSER_IMAGE_DECODING_ENABLED=false

[marandaneto]

@chathu-novade release and dist should match when initing the SDK and uploading source maps.
I see that you don't set the dist at least, do they match?
Can you provide a link to an Sentry's issue?

[marandaneto]

@chathu-novade you probably need --release in your build command line as well.

[ghost]

dist is default so it get build in build/web which also the default of this plugin.

The flutter mobile builds works well Issue is with the web build

[marandaneto]

@chathu-novade I don't see any problem with your errors, its symbolicated correctly.
The issue title is minified:e2b because of https://docs.sentry.io/platforms/flutter/troubleshooting/#known-limitations
See runtimeType.
You are likely calling captureException with an object that is not an exception and its stringified, so there's no problem with symbolication.
Can you clarify the problem?

[ghost]

@chathu-novade you probably need --release in your build command line as well.

--release Build a release version of your app (default mode).

[ghost]

@marandaneto In that error there are errors which says source code not found.

[marandaneto]

@chathu-novade that's already answered here #38 (comment)
If you don't see any frame from your own App, the reason is here #38 (comment)
So I guess that's all from my side unless you provide more context around my questions.

About

The issue title is minified:e2b because of https://docs.sentry.io/platforms/flutter/troubleshooting/#known-limitations
See runtimeType.

Does this applicable to the web too?

web
Obfuscation is not supported for web apps, but a web app can be minified, which is similar. When you build a release version of a Flutter web app, it is automatically minified. For more information, see Build and release a web app.

[marandaneto]

Please raise an issue on https://github.com/getsentry/sentry-dart and provide a minimal reproducible example (this is required), it's unclear what's the problem here since the linked event just works, without more context, we can't help.

Check this issue and expand the stackstrace. We can not see which file threw the exception and not usable stack trace.
