How can I install the android and ios packages … since I see that if I use only react-native they are installed, but not with expo. Thank you.
This is expected for a Managed Expo project. If you need to make native code changes (code found in the
ios directories) you’ll need to use the Bare workflow.
I would recommend reading our docs on the two workflows here: https://docs.expo.io/introduction/managed-vs-bare/ so you can understand all the nuances and decide what is best for your project.
