sha_env 3.0.0

Yet another DotEnv handling library for Dart but all the other gave me headaches.

example/sha_env_example.dart

import 'dart:io';

import 'package:sha_env/sha_env.dart';

void main(final List<String> args) async {
  /// Load the environment variables from a file.
  await load(path: '.env.test');

  /// Check if the environment variable exists.
  if (has('STRING')) {
    print('The environment variable STRING exists.');
  } else {
    print('The environment variable STRING does not exist.');
  }

  /// Get the value of the environment variable.
  final string = getString('STRING');

  print('The value of the environment variable STRING is $string.');

  /// Print all the environment variables.
  env.forEach((final k, final v) => print('$k: $v'));

  exit(0);
}
