Token expiry is 1969-12-31 23:59:59.999Z

The returned token is valid, but the token expiry is 1969-12-31 23:59:59.999Z.

Does this mean it never expires, or does it mean it's expired (even though the token is still valid and can still be used)?

accessToken.isValid() returns false

Could be but no error is thrown on my end. The token is valid but the response I get back from flutter_facebook_login is incorrect. This is due to Facebook returning an expiry date of "-1".

result.accessToken.toMap() returns: {token: aValidTokenHereThatIRemoved, userId: aValidUserIdThatIRemoved, expires: -1, permissions: [manage_pages, public_profile, pages_show_list, email], declinedPermissions: [publish_pages]}

Everything is valid, but the flutter code expects valid epoch time. My presumption was that "-1" meant "non-expiring" so added a check for this: final bool isNonExpiringToken = result.accessToken.expires.millisecondsSinceEpoch == -1; and ignored the returned expiry date from flutter_facebook_login with: expiryDate: isNonExpiringToken ? DateTime.now().add(Duration(days: 60)) : result.accessToken.expires) when saving the credentials with shared_preferences.
