Hi!

We actually don't have a React Native + Segment Target yet. We have a pull request for one here, but it's a bit stale and it doesn't look like it'll cross the finish line. If you like you can create a new one based on what was already done.

Keep in mind that a target doesn't have to be associated with this repo/package at all. You can build and provide your own custom targets for any service: https://rangle.gitbook.io/redux-beacon/examples-and-recipes#how-to-create-your-own-target
