Dart code snippets don't show in-line with stacktraces on the sentry dashboard

Question

Stacktraces from python - beautiful inline code

---

Stacktraces from dart - no inline code snippets :(

---

I understand that python is a super dynamic language and can pick up the code using magic like the inspect module, but is there a way to "give" sentry my dart code too?

Dupe of flutter/#63276

Solution

This is not yet supported.

It might not be possible to add at all since it depends on some level of support from the platform. One approach is to allow users to run sentry-cli to upload a "source bundle" and on the server we lookup the relevant lines of code on that bundle as the events come in. This is done for some platforms.

I'll update this answer if the situation changes.

I made a comment on the GitHub issue too.
