Load environment variables at runtime from a .env file.

Deploying applications should be simple. This implies constraints:

The twelve-factor app stores config in environment variables (often shortened to env vars or env). Env vars are easy to change between deploys without changing any code... they are a language- and OS-agnostic standard.

An environment is the set of variables known to a process (say, PATH, PORT, ...). It is desirable to mimic the production environment during development (testing, staging, ...) by reading these values from a file.

This library parses that file and optionally merges its values with the built-in Platform.environment map.

See documentation and examples.

Get the latest:

$ dart pub global activate dotenv

Run:

$ dart pub global run dotenv:new  # create a .env file and add it to .gitignore
$ dart pub global run dotenv      # load the file and print only the file environment variables to stdout
$ dart pub global run dotenv -p   # load the file and print all the environment variables to stdout
