Accessing Laravel .env variables in blade

I am trying to get some API keys which I have stored in my .env file to use in the blade javascript. I have added two keys like:

APP_ENV=local
APP_KEY=////
APP_DEBUG=true
APP_LOG_LEVEL=debug
APP_URL=http://localhost
APP_GOOGLE_MAPS=////
APP_OVERHEID_IO=////

In blade I need to use the Google Maps API and OverheidIO API key. I have tried getting one of the default .env variables just in case I have formatted the custom .env variables wrong.:

{{ env('APP.ENV') }} // nothing
{{ env('APP_ENV') }} // nothing
{{ env('APP_ENV'), 'test' }} // returns 'test' 

Could someone help me call the google maps api and overheidio api key in the blade?

Five most important commands if your Laravel is not working as expected after some modifications in .env or database folder or because of any other modifications. Here is full explanation: https://www.youtube.com/watch?v=Q1ynDMC8UGg

php artisan config:clear
php artisan cache:clear
composer dump-autoload
php artisan view:clear
php artisan route:clear
