async/retry_policy_utils library

Retry policy (fixed, backoff, jitter) — roadmap #656.

Constants

retryPolicyDefaultBackoffBase → const Duration

Default base delay for exponential backoff in retryWithJitter.

retryPolicyDefaultBackoffJitter → const Duration

Default jitter range for retryWithJitter.

retryPolicyDefaultDelay → const Duration

Default delay between retry attempts.

Functions

retryWithJitter<T>(Future<T> fn(), {int maxAttempts = 3, Duration base = retryPolicyDefaultBackoffBase, Duration jitter = retryPolicyDefaultBackoffJitter, Random? random}) → Future<T>

Exponential backoff with jitter: delay = base * 2^attempt + random(0, jitter).

retryWithPolicy<T>(Future<T> fn(), {int maxAttempts = 3, Duration delay = retryPolicyDefaultDelay, void onRetry(Object error, int attempt)?}) → Future<T>

Retries fn up to maxAttempts with delay between attempts. Optional onRetry.
