flutter强制横屏竖屏设置

void main(){
  // 强制横屏
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.landscapeLeft,
    DeviceOrientation.landscapeRight
  ]);

  runApp(new MyApp());
}

void main(){
  // 强制竖屏
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown
  ]);

  runApp(new MyApp());
}
