The getCookies method may need to be improved

[w4mxl]

When I found a minor problem with the getCookies method, I looked at the source code, on line 224 of base.dart,

final split = cookie.split('=');

If there is also '=' in the cookie value, the result of the split is not correct.

thanks for reporting this. I think this might be related - #351
but I need someone to check if that fixes your issue.
