Retry class
Marks a UseCase or datasource method for automatic retry on failure.
The DDA pipeline generates a retry wrapper that catches retryable failures and re-executes with the configured backoff strategy.
Constructors
-
Retry({int attempts = 3, BackoffStrategy backoff = BackoffStrategy.exponential, Duration maxDelay = const Duration(seconds: 30), Duration baseDelay = const Duration(seconds: 1), Duration? maxCumulativeTime, List<
String> retryOn = const ['network', 'server']}) -
const
- Retry.fixed({int attempts = 3, Duration delay = const Duration(seconds: 2)})
-
Convenience constructor for a simple fixed-delay retry.
