RetryPolicy class abstract

Abstract interface for retry policies

Retry policies determine when and how to retry failed tasks. Implement this interface to create custom retry strategies.

Example:

class MyRetryPolicy extends RetryPolicy {
  @override
  bool shouldRetry(int attempt, Object error, StackTrace stackTrace) {
    return attempt < 3 && error is NetworkException;
  }

  @override
  Duration? nextDelay(int attempt, Object error, StackTrace stackTrace) {
    return Duration(seconds: attempt);
  }
}
