Call for Contributors: OpenTelemetry for Dart and Flutter

Why OpenTelemetry for Dart and Flutter?

Dart is a full-stack language and the language of Flutter, one of the most popular frameworks for building cross-platform applications. Data shows over 20% of current app store submissions are Flutter apps. Dart is null safe and type safe, compiles to fast binaries, and is increasingly used for backend services as well. Yet Dart remains the last top-15 programming language without an officially maintained OpenTelemetry SDK. Earlier community implementations are no longer maintained, leaving Dart and Flutter developers without a supported path to capture telemetry from their servers and apps.

An actively developed implementation of the OpenTelemetry specification for Dart already exists that is in the process of being donated to the the OpenTelemetry project: dartastic_opentelemetry and its standalone API package dartastic_opentelemetry_api, released under Apache 2.0 on pub.dev. It supports traces, metrics, and logs with OTLP/gRPC and OTLP/HTTP exporters across server, desktop, mobile, and web targets.

A Dart and Flutter SIG

The first step to making this an official part of OpenTelemetry is forming a Dart and Flutter Special Interest Group (SIG). A project proposal to bootstrap the SIG is under review, and a donation proposal for the Dart API and SDK is open. Six maintainers across four sponsoring organizations have committed so far — and the long-term success of an official Dart SDK depends on growing that community further.

Call for contributors

If you’re interested in using OpenTelemetry in Dart or Flutter, we need your help! We are looking for contributors who are willing to maintain the codebase, participate in regular SIG meetings, and generally help drive the SDK forward.

If you’re interested in becoming a contributor, or you know someone who might be, please comment on the donation proposal.

If you don’t want to become a contributor but do want to give feedback or try the SDK out, check out the repository and file an issue with your thoughts. All feedback helps the project at this stage.
