Ejecting is an outdated concept when it comes to Expo for the past two years or so. The eject command in the cli is just an alias for the prebuild command even.

The way Expo builds your app these days let's you add native code as you want, modify your Gradle and pods files as needed, and you can still be on their managed workflow where you don't ever need to have Android and iOS folders in your repo. It's a really great time to be using Expo.
