What can I look for to check if a project is set up as a "managed Expo project"

I'm trying to understand React Native development environment. I'm using Visual Code in Windows. I've got a simple project A that I set up using the Expo tutorial as a "Managed Expo Project". Just a simple page and I'm trying to use a checkbox component.

I've got another inherited React Native project B, and I want to find out if it's a "Managed Expo Project" or a "Bare React native" project. It does include Expo, but I have read that even a Bare React Native Project can include expo.

So: Is there a setting on a line in a config file somewhere that makes it one or the other? ie Does the existence of "expo": "~40.0.0", in dependencies in package.json define it?

(I came to this point because I'm trying to use CheckBox from "@react-native-community/checkbox". Project B builds fine when using this, but my simple project A does not. I see on Expo website that this does not work with Expo, and that we are supposed to use a component Expo-Checkbox instead. SO I wanted to confirm the 2 projects are both expo-managed.)

Thank you.

expo react-native

Run expo diagnostics in your project and it will tell you what workflow you're using. The heuristics used to determine your project type are:

  1. do you have an ios directory or android directory?
  2. do you have react-native-unimodules in your package.json?

Usually people end up with a bare workflow project by accident when they eject and then don't properly revert their project once they decide to abort.
