isAuthenticated abstract method

Future<bool> isAuthenticated()

Called to check if this instance has a valid authentication nounce and generateAuthUrl() won't return null.

This function will be called before init() function, therefore if you are using client instance passed through init() then there will be NullReferenceException.

If you require HTTP requests in this method, then you need to implement custom logic.

Implementation

Future<bool> isAuthenticated();
