parseHeader('subscription-state') throws exception

[Perondas]

When parsing a sunscription-state header with the value "active;expires=899" using the parseHeader function a runtime exception is thrown in the grammar parser.

E/flutter (11218): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: type 'List<dynamic>' is not a subtype of type 'int?'
E/flutter (11218): #0      GrammarParser._parse_subexp_params.<anonymous closure>

To Reproduce
Steps to reproduce the behavior:

1. Call dart Grammar.parse("active;expires=899", "Subscription_State");

Closed with #269

Hi mate,
I think the error still occurs, it seems like it is not being able to parse the entire NOTIFY message, did the #269 solved it to you @Perondas ?

Thanks a lot!

@loladinha96 strange. The grammar was faulty, but I fixed it in #317. I assume you are downloading the lib from pub? Because there has been no release ever since August. That fix is therefore not out yet. I will look into releasing it.
Once that is done, please report if the issue still persists.

@Perondas thanks a lot for the quick reply mate.

Ok I understand I also tryed to play a bit with the grammar parser inside the lib but without much success and haven't gone more further because Im pulling it from the pub and didn't want to take the chance of loosing the "selfmade fix".

But yeah sounds really good, really appreciate it.
I will keep an eye on the lib to check when a new release gets done and will be happy to give a feedback afterwards.
Cheers
