+The default behavior for this SDK is to use the `identifiedOnly` mode of person processing, but this can be changed in the config. The options are:
+- `PostHogPersonProfiles.identifiedOnly`
+- `PostHogPersonProfiles.never`
+- `PostHogPersonProfiles.always`

 To set up [session replay](/docs/session-replay) in your project, all you need to do is install the Flutter SDK and enable "Record user sessions" in [your project settings](https://us.posthog.com/settings/project-replay).
 
+If you're using the `canvaskit` renderer, also enable the "Canvas capture" in [your project settings](https://us.posthog.com/settings/project-replay).
