flutter 的一些基础设置

1、设置app整体状态栏颜色

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.light);

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle.dark);

深色or浅色，在main函数中设置

2、自定义app主题色

flutter的主题色内置的，如果想自定义，就要自定义MaterialColor

  static const int _bluePrimaryValue = 0xfff6ffef;  static const MaterialColor themeGreen = MaterialColor(    _bluePrimaryValue,    <int, Color>{      50: Color(_bluePrimaryValue),      100: Color(_bluePrimaryValue),      200: Color(_bluePrimaryValue),      300: Color(_bluePrimaryValue),      400: Color(_bluePrimaryValue),      500: Color(_bluePrimaryValue),      600: Color(_bluePrimaryValue),      700: Color(_bluePrimaryValue),      800: Color(_bluePrimaryValue),      900: Color(_bluePrimaryValue),    },  );

  return MaterialApp(      title: 'test',      theme: ThemeData(          primarySwatch: themeGreen, textSelectionColor: WorkColor.colorHint),      onGenerateRoute: router.generateRoute,      debugShowCheckedModeBanner: false,      initialRoute: 'home',    );  }

3、app设置中文

flutter默认语言是英语，一般情况使用不到这个默认语言，但是如果用到系统功能，比如长按粘贴复制，就需要更改语言

 return MaterialApp(    localizationsDelegates: [      GlobalMaterialLocalizations.delegate,      GlobalWidgetsLocalizations.delegate,      ChineseCupertinoLocalizations.delegate,    ],    supportedLocales: [      const Locale('zh', 'CN'),      const Locale('en', 'US'),    ],
    、、、、  );}

4、禁止app的自动旋转：

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

在main函数中设置

基于此方法就可以设置app中在某些页面强制横屏，方法如下：

@override
void initState() {
  super.initState();
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.landscapeRight,
    DeviceOrientation.landscapeRight,
  ]);
}
@overridevoid dispose() {
  SystemChrome.setPreferredOrientations([
    DeviceOrientation.portraitUp,
  ]);
  super.dispose();
}

but，此方法在ios上并不适用

找来找去，找到了个插件（pub.dev/packages/or…
