我正在尝试创建反应本机应用程序。但它是抛出错误。我使用了反应原生导航。 (我正在尝试创建反应本机应用程序。但它是抛出错误。我使用了反应原生导航。)

import { createAppContainer, createSwitchNavigator } from "react-navigation";
import { createStackNavigator } from "react-navigation-stack";
import { createBottomTabNavigator } from "react-navigation-tabs";
import DashboardScreen from "./src/component/Dashboard";
import LoginScreen from "./src/component/Auth/Login";
import RegisterScreen from "./src/component/Auth/Register";
const AppStack = createStackNavigator({ Dashboard: DashboardScreen });
const AuthStack = createBottomTabNavigator({
SignIn: LoginScreen,
Register: RegisterScreen
});
export const RootNaviation = () => {
return createAppContainer(
createSwitchNavigator(
{
Auth: AuthStack,
App: AppStack
},
{ initialRouteName: "Auth" }
)
);
}; 

应用文件

import React from "react";
import { StyleSheet, Text, View, Button } from "react-native";
import { SwitchNavigator } from "./Router";
const Nav = SwitchNavigator();
export default function App() {
return (
<View style={styles.container}>
<Button title="dafdlka" />
<Nav />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: "#fff",
alignItems: "center",
justifyContent: "center"
}
});

您从未创建过名为SwitchNavigator的变量。

您可以使用RootNaviation

import { RootNaviation } from "./Router"
...
export default function App() {
return (
<View style={styles.container}>
<Button title="dafdlka" />
<RootNaviation />
</View>
);
}
