Support Timber tags

[romtsn]

We have no way to get the tag when inheriting Timber.Tree, because it's marked as internal/package-private for consumers https://github.com/JakeWharton/timber/blob/dc45d69b081a03e3fb83e81a7aee0f430f46b4f1/timber/src/main/java/timber/log/Timber.kt#L22. This means, when timber is used like this:

Timber.tag("Tag")
Timber.e("Issue")

the tag will not be reflected on Sentry.

If this gets traction, we could either offer a reflection-based support or automatically infer classname of the caller (that's what Timber.DebugTree does by default).

Please, vote on this issue if you'd like us to provide support for Timber tags.

Would they accept a PR upstream that adds an API to get the tags?

[romtsn]

There is actually a few open PRs addressing that (this is the closest one to what we want https://github.com/JakeWharton/timber/pull/224/files), but none of them get any traction unfortunately.

We can try but JakeWharton/timber#393 never got a reply/review.
