null is not an object (evaluating 'RCTToastAndroid.SHORT')

I am attempting to convert my react-native project into an expo project, one small issue I've encountered is when I run the expo project I get an error as such

null is not an object (evaluating 'RCTToastAndroid.SHORT')

After doing some research online on how to fix this problem a user requested that a problem like this can simply be resolved by removing the Android part of RCTToastAndroid.SHORT this user stated that RCTToast is universally compatible with both iOS and Android. However when I do this I receive an error saying null is not an object (evaluating 'RCTToast.SHORT')

What can I do that will help ease the transition from my react-native project to an expo project?

I had the same exact problem.

Check to see if you've imported a library called 'react-native-simple-toast'. Remove it from your dependencies.

According to this issue:

this library has a custom native module for ios, and expo does not support that. This lib will not work with expo

it will only work with a bare React Native project.

If you do need to use Toasts

Here's a library that will work with Expo on both Android and iOS. The only downside is that it's pure Javascript.

You can use it like this:

import Toast from 'react-native-root-toast'

Toast.show('Your message here', {
    duration: Toast.durations.SHORT,
    position: Toast.positions.BOTTOM,
    shadow: true,
    animation: true
});

All apps created with create-react-native-app, are compatible with Expo CLI without changes.
