Error "object is unsendable" when using TalkDioLogger inside isolate

[berbsd]

I am curious if anyone has seen this problem before. I don't have a small code sample to repro at this time, but can put one together if really needed.

I am using a shared instance of Dio between my main thread and different isolates. It works well, unless I use the TalkerDioLogger with the main talker instance declared in my main function. In this case, the error below happens constantly. If I remove talker, then everything works flawlessly. It is 100% repeatable for me (and annoying).

I tried different ways to implement my isolates but to no avail. if I add interceptor to the shared client within the isolate with a separate instance of talker, then no issues, but logs are not visible at all.

Any pointers would be greatly appreciated.

Thx

David
