启用设备屏幕旋转横向或纵向，仅适用于平板设备 by Flutter

Question

我想让我的应用程序屏幕仅适用于平板电脑横向或纵向。 Still on Portrait for smart 应用程序由 Flutter 开发。

Answer 1

检查设备是平板电脑

class DeviceUtil {
  static String get _getDeviceType {
    final data = MediaQueryData.fromWindow(WidgetsBinding.instance.window);
    return data.size.shortestSide < 550 ? 'phone' : 'tablet';
  }

  static bool get isTablet {
    return _getDeviceType == 'tablet';
  }
}

DeviceUtil.isTablet; //true

使用这个

  if(DeviceUtil.isTablet){
     //landscape-or-potrait
}else{
//landscape-or-potrait
}

Answer 2

您可以使用SystemChrome设置肖像

final data = MediaQueryData.fromWindow(WidgetsBinding.instance!.window);
if(data.size.shortestSide > 600) { // check if its bigger
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown,
  ]);
} else { // otherwise will be ..
    SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
  ]);
}
