Flutter中One Signal真机无法推送通知问题排查

模拟器中可正常运行，但在真机上控制台返回Prompted But Never Answered错误，提示需移除其他通知SDK或请求权限代码，推测与Firebase FCM有关，但无法找到对应的权限请求代码。

OneSignal初始化代码 #

WidgetsFlutterBinding.ensureInitialized();
await EasyLocalization.ensureInitialized();
OneSignal.Debug.getDeviceState().then((value) {});
OneSignal.Notifications.requestPermission(true);
try {
  OneSignal.Debug.setLogLevel(OSLogLevel.verbose);
} catch (e) {

Android端崩溃信息 #
