Trying to have Play Services Log in, and nice-to-haves are Leaderboard and Achievements

I’m using ReactJS and CapacitorJs and would like Play Services to work.
As far as I’m aware, I can still use Native Features.
I keep getting errors on the plugins I’ve tried.

Are there plugins you’ve used and know still work?

It depends on what you’re trying to do exactly. I don’t think there’s a capacitor-play-services plugin as far as I’m aware.

But it is possible to build native features! If you know what you need, you could always try building your own plugin. There’s an example doc here on how to do that in Android. Capacitor - build cross platform apps with the web
