Sentry Structured Logs for Dart/Flutter

[buenaflor]

https://develop.sentry.dev/sdk/telemetry/logs/

Sentry is adding support for structured logging.

1. Define the logs protocol and log envelope item in the SDK
2. Add the Public API (SDK options and methods) as per the docs
3. Create a GH discussion that contains instructions for setting up the SDK in your repo. Eventually this will be moved into the primary docs. See the JS SDK's GH discussion for inspiration.

Out of Scope

• We dont want to add logs to integrations yet, we only want to provide the API for now

@buenaflor @denrase I added a third item here re: creating a GH discussion for temporary docs

We can use that to gather feedback on docs and iterate before moving it into the docs repo.

@AbhiPrasad Dart doesn't have a built-in way to format parameterized strings, we'd need to implement it ourselves, should we prefer implementing printf format?

[AbhiPrasad]

we'd need to implement it ourselves

How difficult would this be? If the language doesn't support any kind of templating, I'm comfortable with just shipping the first release without it, and coming back to this at a later time (we could even open a feature request GH issue and monitor user feedback).

We've decided to not implement it for the initial release, I'll open a feature request GH issue
