Fixing Expo Stuck on “Welcome to Expo” Screen

If you’re facing the issue where your Expo app is stuck on the “Welcome to Expo” screen, it might be due to the incompatibility of the react-native-dotenv package with expo-router. This problem can cause the environment variable configuration to fail.

Steps to Resolve:

  1. Uninstall react-native-dotenv: Run npm uninstall react-native-dotenv to remove the package.
  2. Update babel.config.js: Replace your current config with this:
    module.exports = function (api) {
    api.cache(true);
    return {
    presets: ['babel-preset-expo']
    };
    };
  3. Access Environment Variables: Instead of using react-native-dotenv, access environment variables directly using process.env.X throughout your application.
  4. Clear Cache: Run npx expo start -c to clear the cache and restart your Expo project.

Conclusion:

By removing react-native-dotenv and ensuring the right Babel preset, your Expo app should work fine. For more details on environment variables in Expo, check the official documentation.

  3. Thanks for the suggestions you have discussed here. Also, I believe usually there are some factors that really keep your motor insurance premium straight down. One is, to take into account buying cars and trucks that are in the good directory of car insurance providers. Cars that are expensive are usually more at risk of being robbed. Aside from that insurance coverage is also depending on the value of your vehicle, so the costlier it is, then the higher the premium you make payment for.
