RetryPolicy.fixed({
  1. int maxRetries = 3,
  2. Duration interval = const Duration(seconds: 1),
})

固定间隔重试的工厂方法（兼容旧 API 行为）

Implementation

factory RetryPolicy.fixed({
  int maxRetries = 3,
  Duration interval = const Duration(seconds: 1),
}) {
  return RetryPolicy(
    maxRetries: maxRetries,
    strategy: RetryStrategy.fixed,
    baseInterval: interval,
  );
}
