-/// A class for obtaining credentials via an [authorization code grant][]. This
-/// method of authorization involves sending the resource owner to the
-/// authorization server where they will authorize the client. They're then
-/// redirected back to your server, along with an authorization code. This is
-/// used to obtain [Credentials] and create a fully-authorized [Client].
-///
-/// To use this class, you must first call [getAuthorizationUrl] to get the URL
-/// to which to redirect the resource owner. Then once they've been redirected
-/// back to your application, call [handleAuthorizationResponse] or
-/// [handleAuthorizationCode] to process the authorization server's response and
-/// construct a [Client].
