Description

Hi,

I'd like to retry if the returned object meets a condition.

Example:

      final response = await retry(
      // Make a GET request
      () => http.get('https://google.com'),
      // Retry on Exception
      retryIf: (e) => e is SocketException,
      retryIfReturnedObject: (o) => o == "retry-please"
  );

is this possible? Thanks

Contributor guide

Research direction
Implement a new optional parameter 'retryIfReturnedObject' in the retry function that allows retrying based on the returned value. Modify the retry logic to check the return value against the condition provided.
