wechat_kit 5.0.3 微信授权不成功

[pen110]

late final StreamSubscription _respSubs;

void onInit() async {
super.onInit();
_respSubs = WechatKitPlatform.instance.respStream().listen(_listenResp);
}
void _listenResp(WechatResp resp) {
print('object--111--');
if (resp is WechatAuthResp) {
print('object-2222---');
final String content = 'auth: ${resp.errorCode} ${resp.errorMsg}';
print('登录----$content');
}
}

调用bindWechat(){
WechatKitPlatform.instance.auth(
scope: [WechatScope.kSNSApiUserInfo],
state: 'auth',
);
}
但是这个监听没有被调用respStream().listen
