Flutter SDK docs incomplete

[ospaarmann]

Hi,

the docs at https://pub.dev/documentation/onesignal_flutter/latest/ are incomplete. Functions like addEmail or removeEmail are completely missing. This makes it harder to set up the SDK and doesn't necessarily increase trust in the service. And the build for the SDK is marked as failing...

Would be great if you could look into that. I was for example not aware that there is a removeEmail function, because an older version of the docs did describe addEmail but not removeEmail and your support told me that this has to be solved via the unsubscribe link in emails. Now both functions are not documented anymore.

Thanks!
