The purpose of sendWeChatAuth is to get auth code and then get information for WeChat login.
Getting access_token is not supported in fluwx. For access_token, please visit official documents.
Fluwx fluwx = Fluwx();
fluwx.authBy(which: NormalAuth(scope: 'snsapi_userinfo', state: 'wechat_sdk_demo_test'));Please refer to example for more details。
WHY? I think we shall fetch access_token or user info at backend.
