feat(envelope-item): Support span type #4935

buenaflor · 2025-11-25T12:22:55Z

📜 Description

Span First initiative - this PR is needed for Dart/Flutter right now but will be needed in general in the future when Java also implements span first

💡 Motivation and Context

See span protocol https://develop.sentry.dev/sdk/telemetry/spans/span-protocol/

Needed for processing envelope items with type span.

Currently needed in Flutter's span first implementation as we rely on Java's InternalSentrySdk.captureEnvelope. Without this support the envelope item type is set to unknown when you use captureEnvelope and the span won't be ingested

💚 How did you test it?

Unit test and manually tested together with the Sentry Flutter SDK

📝 Checklist

I added GH Issue ID & Linear ID
I added tests to verify the changes.
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
I updated the docs if needed.
I updated the wizard if needed.
Review from the native team if needed.
No breaking change or entry added to the changelog.
No breaking change for hybrid SDKs or communicated to hybrid SDKs.

sentry/src/main/java/io/sentry/SentryItemType.java

  CheckIn("check_in"),
  Feedback("feedback"),
  Log("log"),
+  Span("span"),
  Unknown("__unknown__"); // DataCategory.Unknown

  private final String itemType;


valid concern but I am not sure if we need to handle this now since we cannot capture spans directly from the java sdk anyway

hm, I think it's still valid even for the hybrid SDKs because client reports are counted from the unsent envelop items? But anyway, it can be done in a follow up PR later

I'll double check this

LGTM, maybe create a followup issue to address the client reports/rate limiter concern?
