PaystackConfig

PaystackConfig({
  required String publicKey,
  required String secretKey,
  Environment environment = Environment.test,
  LogLevel logLevel = LogLevel.info,
  RetryPolicy retryPolicy = const RetryPolicy(),
  String currency = 'NGN',
  String locale = 'en',
  Duration? timeout,
})

Also: fromEnvironment() reads compile‑time env values.
