我正在尝试通过AppContainer传递道具。我能够传递其他组件的信息，但是我不知道如何通过createAppContainer发送道具
在App.js中：
render() {
return (
this.state.isLoggedIn ? <DrawerNavigator /> :
<SignedOutNavigator handler={this.saveUserSettings} />
)
}
在SignedOutNavigator中：
import React from "react";
import { View, Text } from "react-native";
import { createStackNavigator, createAppContainer } from "react-navigation";
import LoginScreen from "../screens/LoginScreen";
const SignedOutNavigator = createStackNavigator({
Login: {
// screen: LoginScreen
screen: props => <LoginScreen screenProps={value => {
// I need to access props from here
// like this.props.handler(value)
}} />,
navigationOptions: ({ navigation }) => ({
header: null,
}),
}
});
export default createAppContainer(SignedOutNavigator);

好的，我得到了Samuel Vaillant的帮助。我不得不做一些修改。
我的App.js：
render() {
return (
this.state.isLoggedIn ? <DrawerNavigator /> : <SignedOutNavigator
screenProps={{
handler: (settings) => { this.saveUserSettings(settings) }
}}
/>
)
}
我的SignedOutNavigator：
import React from "react";
import { View, Text } from "react-native";
import { createStackNavigator, createAppContainer } from "react-navigation";
import LoginScreen from "../screens/LoginScreen";
const SignedOutNavigator = createStackNavigator({
Login: {
// screen: LoginScreen
screen: screenProps => <LoginScreen screenProps={value => {
screenProps.screenProps.handler(value)
}} />,
navigationOptions: ({ navigation }) => ({
header: null,
}),
}
});
export default createAppContainer(SignedOutNavigator);

您必须将道具置于screenProps下，才能在public class RequestEattest {
