I am using FlutterAppAuth.authorize() to obtain the authorization code directly, instead of using FlutterAppAuth.authorizeAndExchangeCode. However, when I try to use the authorization code, I encounter an error stating that it has already been used.
How can I resolve this issue? Please provide suggestions as soon as possible.
