CastError when initializing #15

Closed SlayerOrnstein closed 3 years ago

SlayerOrnstein commented 3 years ago

Matomo seems to be throwing and error when initializing, started to happen when updating to 0.1.1.

_CastError: type '_InternalLinkedHashMap<String, String?>' is not a subtype of type 'Map<String, String>?' in type cast

This seems to be in the send method. We dequeue messages in the initialize method which ends up sending messages.

In particular, the crash seems to be when we cast the headers:

headers as Map<String, String>?

This is strange but might be due to a newer version of dart that I've been using. (I've been stuck to pre-nullsafety for my main project because other libraries haven't moved yet)

Could you send me the version of dart you are using?

I'll look into this crash over the weekend.

Yeah, sorry I didn't include it from the start.

I had the same problem. I've fixed it and opened a PR: https://github.com/poitch/dart-matomo/pull/16
