Typing for extra

[moshe5745]

Request Statement

Right now there is no typing for extras that could be passed to the request.
For instance, we want to pass some extra data to the interceptor.

What does typing help here? You can always safely cast fields by using is.

A generic way to pass data to the interceptor.
Cleaner code I guess.

Guess you're right. This feature is not needed. After I understood the power of is

Also pattern matching is great when destructing extras. See https://dart.dev/language/patterns#validating-incoming-json.

Cant pattern match with class on the map object. Too bad...

If I have a class like:

class RequestMetadata {
  final int code;

  RequestMetadata({required this.code});
}

I can pattern match it on interceptor only with this

  var code = switch (options.extra) { {"code": int code} => code, _ => "" };

Not a perfect situation.
