强制横屏：

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

 

 

强制竖屏：

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

 

 

以上代码写在main.dart文件中
