I saw this reddit post: https://www.reddit.com/r/FlutterFlow/comments/1bip4si/any_idea_how_to_add_posthog_analytics_to_a/
Official documentation:
https://posthog.com/docs/libraries/flutter
But I'm personally still quite confused about how to add posthog into Flutterflow and would really appreciate it if someone has good step-by-step instructions.
