Flutter-获取唯一的设备ID [英] Flutter - Get Unique Device ID

问题描述

我正在使用基于令牌的系统制作一个应用程序.因此，用户可以购买令牌并使用令牌进行一些操作. 使用电子邮件和密码创建帐户后，每个用户均可免费获得10个令牌(作为试用版).

I am making an app with token based system. So users can buy tokens and using them they can make some actions. Each user gets 10 tokens for free (as a trial version) after creating an account using email and password.

我想通过每次获取一个新帐户来防止该用户再获得10个令牌，我想知道Android和iOS设备是否都具有唯一的设备ID?

I want to prevent that user gets another 10 tokens by getting a new account each time and I was wondering if there is something like unique device ID for both Android and iOS devices?

我可以为此目的使用它吗? https://pub.dartlang.org/packages/device_id#-example-tab -

Can I use this for that purpose? https://pub.dartlang.org/packages/device_id#-example-tab-

推荐答案

使用开发的 device_info 插件由Flutter团队本身负责.这是您在两个平台上都可以获取ID的方法.

Use device_info plugin developed by Flutter team itself. This is how you can get IDs on both platform.

在您的pubspec.yaml文件中添加以下内容:

In your pubspec.yaml file add this:

dependencies:
  device_info: any

创建方法:

Future<String> _getId() async {
  DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
  if (Theme.of(context).platform == TargetPlatform.iOS) {
    IosDeviceInfo iosDeviceInfo = await deviceInfo.iosInfo;
    return iosDeviceInfo.identifierForVendor; // unique ID on iOS
  } else {
    AndroidDeviceInfo androidDeviceInfo = await deviceInfo.androidInfo;
    return androidDeviceInfo.androidId; // unique ID on Android
  }
}

使用方式如下:

Use it like:

String deviceId = await _getId();

或

_getId().then((id) {
  String deviceId = id;
});
