dart - 如何从 Flutter 检查设备操作系统版本？

Question

Platform.operatingSystem 将告诉您是在 Android 还是 iOS 上运行。

如何检查我运行的是哪个版本的设备操作系统？

Answer 1

将此插件添加到您的 pubspec device_info

人类可读的方式是

if (Platform.isAndroid) {
  var androidInfo = await DeviceInfoPlugin().androidInfo;
  var release = androidInfo.version.release;
  var sdkInt = androidInfo.version.sdkInt;
  var manufacturer = androidInfo.manufacturer;
  var model = androidInfo.model;
  print('Android $release (SDK $sdkInt), $manufacturer $model');
  // Android 9 (SDK 28), Xiaomi Redmi Note 7
}

if (Platform.isIOS) {
  var iosInfo = await DeviceInfoPlugin().iosInfo;
  var systemName = iosInfo.systemName;
  var version = iosInfo.systemVersion;
  var name = iosInfo.name;
  var model = iosInfo.model;
  print('$systemName $version, $name $model');
  // iOS 13.1, iPhone 11 Pro Max iPhone
}
