📋 Changes

This error is happening because in Java we were parsing the credentials result as Z which refers to timezone parsing in Java

But this was later changed to escape as shown below.

This means we were initially parsing the timestamp as UTC at the dart layer when credentials were retrieved and to be same as that we had to set timezone while saving the credentials.

But after that we have removed parsing timezone by escaping the Z with quotes ''. But we haven't removed the timezone being set in save credentials handler. This caused the time to jump to the offset of UTC.

We have fixed this by removing the timezone in save credentials handler.

🎯 Testing

Existing unit test has been fixed to avoid this issue

Wasn't the Z escaped in this PR: https://github.com/auth0/auth0-flutter/pull/238?

In fact, we requested the escaped format:

Are we sure this change won't re-introduce this issue? https://github.com/auth0/auth0-flutter/issues/160

Yes, escaping it would be the right thing. But while we escaped the timezone "Z" which will parse the date to local time, we have forgotten to remove

format.timeZone = TimeZone.getTimeZone("UTC")

Also this would have caused issues for API login and other places since it was set only here and not in the other places where we format date

[Widcket]

It'd be great to have a single date formatter (or format string) in the entire Android native layer, to avoid these kinds of issues.

This fixes the token refesh issue for me. Please merge it

We're needing this released as well as it's affecting our users
