loadFromEnv method

void loadFromEnv({ Map<String, String>? overrideEnv, })

Read well-known environment variables and store them in the global scope.

Implementation

void loadFromEnv({Map<String, String>? overrideEnv}) {
  final env = overrideEnv ?? Platform.environment;
  for (final entry in _envMapping.entries) {
    final envValue = env[entry.key];
    if (envValue != null && envValue.isNotEmpty) {
      final configKey = entry.value;
      dynamic parsed = envValue;
      // Attempt numeric / bool coercion.
      if (int.tryParse(envValue) != null) {
        parsed = int.parse(envValue);
      } else if (double.tryParse(envValue) != null) {
        parsed = double.parse(envValue);
      } else if (envValue.toLowerCase() == 'true') {
        parsed = true;
      } else if (envValue.toLowerCase() == 'false') {
        parsed = false;
      }
      _store[ConfigScope.global]![configKey] = parsed;
      _sources[ConfigScope.global]![configKey] = ConfigSource.env;
    }
  }
