鸿蒙设备工具类

Flutter代码调用

• 创建通道
  static const MethodChannel _channel = const MethodChannel('device_util');
• 获取version name

  /// The version name of this application
  static Future<Stringget versionName async {
final String version = await _channel.invokeMethod('getVersionName');
return version;
  }

• 获取version code

  /// The version code name of this application
  static Future<Stringget versionCode async {
final String version = await _channel.invokeMethod('getVersionCode');
return version;
  }

• 打开手机的网络设置页面

      /// Open the phone's network settings page
  static Future<NullopenNetworkSettingPage() async {
await _channel.invokeMethod('launchNoNetwork');
  }

• 打开手机设置页面

   /// Open the settings page of the currently running application
    static Future<NullopenApplicationSettingPage() async {
  await _channel.invokeMethod('systemSettingPage');
    }

• 获取手机信息

     static Future<Map<String, String>get getChannelInfo async {
final Map<String, StringchannelInfo =
Map<String, String>.from(await _channel.invokeMethod('getChannelInfo'));
return channelInfo;
  }

• 终止当前应用程序进程并退出

      /// Kill the current application process and exit (Only supports Android)
  static Future<NullkillApp() async {
await _channel.invokeMethod('killApp');
  }
