如何在颤动中将应用程序强制为人像模式 [英] How to force the application to Portrait mode in flutter

问题描述

void main(){
  ///
  /// Force the layout to Portrait mode
  /// 
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown
  ]);

  runApp(new MyApp());
}

推荐答案

将此代码放入MyApp()中，不要忘记导入服务包:

Put this code in the MyApp() and don't forget to import the services package:

  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
    DeviceOrientation.portraitDown,
  ]);

像下面这样:

import 'package:flutter/services.dart';

class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
      SystemChrome.setPreferredOrientations([
        DeviceOrientation.portraitUp,
        DeviceOrientation.portraitDown,
      ]);
      return new MaterialApp();
    }
  }
