从“React”导入React；
从“react native”导入{TouchableOpacity，Text，TextInput，View，KeyboardAvoidingView}；
从“./styles”导入{styles}；
从“../../components/Logo”导入{Logo}；
从“./../prefacts/colors”导入{hintColor}”；
类签名扩展了React.Component{
gotoHomeScreen=（）=>{
这个.props.navigation.navigate（“Home”）；
};
render（）{
返回(
this.passwordInput.focus（）}
自动更正={false}
keyboardType='email-address'
returnKeyType=“下一步”
占位符=“电子邮件”
占位符文本颜色={hintColor}/>
this.passwordInput=input}
占位符=“密码”
占位符textcolor={hintColor}
secureTextEntry/>
登录
);
}
}
导出默认签名；
这段代码到底出了什么问题以及如何修复它？

我通过如下更改我的
MainScreenNavigation.js
来消除这个错误

MainScreenNavigation.js

import { createAppContainer, createSwitchNavigator, createStackNavigator } from "react-navigation";
import Splash from '../screens/Splash/Splash';
import Signin from '../screens/Signin/Signin';
// import HomeScreen from '../screens/Home/HomeScreen';
// import Profile from '../screens/Profile/Profile'

export const MainScreenNavigation = createAppContainer(createSwitchNavigator({
    Splash: Splash,
    Main: SigninNavigator,
},  {
        initialRouteName: 'Splash'
    },
)
);

const SigninNavigator = createSwitchNavigator({
    Signin: Signin,
    // Home: HomeNavigator,
},  {
        initialRouteName: 'Signin'
    },
);

// const HomeNavigator = createStackNavigator({
//     Profile: Profile,
//     HomeScreen: HomeScreen,
// },
//     {
//         initialRouteName: 'HomeScreen'
//     }
// );

在其他一切实际影响输出之前声明导出appContainer？
