This issue serves to gather interest and comments regarding Profiling for RN.

More about the Profiling product here.

Android and iOS support profiling therefore RN native could offer an option to turn it on in the native layers.

Thumbs up if you are interested.

Right now that would be possible if you init the SDK manually.

Enable Performance and Profiling directly on the Native SDKs, for example, Android.
https://docs.sentry.io/platforms/android/performance/
https://docs.sentry.io/platforms/android/profiling/

The same steps for iOS, would work for Android and iOS native code only, not in the JS bits nor C bits for Android.

[marandaneto]

@krystofwoldrich is there a draft PR we can look at? no need to be finished or polished, the earlier a draft PR is out, the earlier you get feedback :)

[krystofwoldrich]

Yes, there is.
