getList method

@override List<String> getList(String key, { String separator = ',', List<String> defaultValue = const [], })

Retrieves a list of strings from an environment variable.

Splits the value using the specified separator and trims whitespace from each element.

// With ALLOWED_HOSTS="localhost,127.0.0.1,::1"
final hosts = env.getList('ALLOWED_HOSTS');
// Returns: ['localhost', '127.0.0.1', '::1']

// With semicolon separator
final paths = env.getList('PATHS', separator: ';');

Implementation

@override
List<String> getList(
  String key, {
  String separator = ',',
  List<String> defaultValue = const [],
}) {
  final value = _env[key];
  if (value == null || value.isEmpty) return defaultValue;
  return value.split(separator).map((e) => e.trim()).toList();
}
