registerHandler method

bool registerHandler(
  1. ErrorHandler handler
)

Register a callback which can handle errors.

The callback can answer with an updated request that can resolve the authentication error.

If the callback can't handle the error, then it should return null. The authenticator will then try using the next registered handler to try to fix the authentication issue.

Implementation

bool registerHandler(ErrorHandler handler) {
  return _handlers.add(handler);
}
