I am having a project here, using Expo managed workflow. When I run it on my physical device, it just crashes and says 'Unfortunately Expo has stopped'. The crash occurs in the MapScreen.js file. I use ->

• react-native-modal
• lottie-react-native
• react-native-router-flux
• firebase

You can help me if you study the code. Actually, I have to do something very simple, but I don't know what to do.
