[buenaflor]

Adds support for uploading dart symbol maps that are associated via debug id extracted from the provided debug file

example usage:

sentry-cli dart-symbol-map upload --org my-org --project my-proj /path/to/mapping /path/to/debug-file

Tests:

• integration tests
• manual tests of uploading to the test sdk repo on sentry

Part of getsentry/sentry-dart#2805

I'll try to do a fuller review before I head into vacation from Tuesday afternoon – but in case I don't get to, and you request review from someone else, just want to leave an initial thought here:

I would suggest that instead of naming this command sentry-cli upload-dart-symbol-map, we name it sentry-cli dart-symbol-map upload.

The reason is that this aligns with the APIs for debug-files upload and sourcemaps upload. Also, this would then mean we have a dart-symbol-map subcommand, with an upload command nested below. That way, if we ever want to add more functionality related to Dart symbol maps, we can also add this functionality under the dart-symbol-map subcommand.

Thanks, will update the command

[szokeasaurusrex]

As currently written, this command will use way more memory than needed. Please address these, and also restructure the code as requested.

Feel free to dismiss my review once fixing these, if I am still on vacation

LGTM. Have you verified that it works with Sentry?
