Are you by any chance using Sentry? Sentry uses Breadcrumbs for their sort of "stack trace" feature.

When using Sentry, I also appear to get this issue due to OkHTTP logs being pretty printed out by pretty_dio_logger.

I am uncertain if Breadcrumbs are used in any other common libraries, but to me it seems largely like a Sentry construct.
