How to use react-navigation's withNavigation in typescript?

问题

I'm trying to use react-native, react-navigation and typescript together to create an app. There are only two screens(HomeScreen and ConfigScreen) and one component(GoToConfigButton) in total, as follows.

HomeScreen

import React from "react";
import { NavigationScreenProps } from "react-navigation";
import { Text, View } from "react-native";
import GoToConfigButton from "./GoToConfigButton";

export class HomeScreen extends React.Component<NavigationScreenProps> {
  render() {
    return (
      <View>
        <Text>Click the following button to go to the config tab.</Text>
        <GoToConfigButton/>
      </View>
    )
  }
}

GoToConfigButton

import React from "react";
import { Button } from "react-native";
import { NavigationInjectedProps, withNavigation } from "react-navigation";

class GoToConfigButton extends React.Component<NavigationInjectedProps> {
  render() {
    return <Button onPress={this.handlePress} title="Go" />;
  }
  private handlePress = () => {
    this.props.navigation.navigate("Config");
  };
}
export default withNavigation(GoToConfigButton);

The code for ConfigScreen is not given because it's not important here. Well, actually the above code works, I can go to the config screen by clicking on the button. The problem is, Typescript thinks I should provide the navigation property to GoToConfigButton manually.

<View>
  <Text>Click the following button to go to the config tab.</Text>
  <GoToConfigButton/>  <-- Property "navigation" is missing.
</View>

How can I tell Typescript that the navigation property is given automatically by react-navigation?

回答1:

You were just missing Partial<> interface wrapping your NavigationInjectedProps as it is described in this pull request where this issue was fixed.

import React from "react";
import { Button } from "react-native";
import { NavigationInjectedProps, withNavigation } from "react-navigation";

class GoToConfigButton extends React.Component<Partial<NavigationInjectedProps>> {
    render() {
        return <Button onPress={this.handlePress} title="Go" />;
    }

    private handlePress = () => {
        this.props.navigation.navigate("Config");
    };
}

export default withNavigation(GoToConfigButton);

Tested with @types/react-navigation >= 2.13.0

import styles from "./styles";

import React, { PureComponent } from "react";

import { Button } from "react-native-elements";
import {
  DrawerItems,
  NavigationInjectedProps,
  SafeAreaView,
  withNavigation
} from "react-navigation";

class BurgerMenu extends PureComponent<NavigationInjectedProps> {
  render() {
    return (
      <SafeAreaView style={styles.container} >

        <Button
          icon={{ name: "md-log-out", type: "ionicon" }}
          title={loginStrings.logOut}
          iconContainerStyle={styles.icon}
          buttonStyle={styles.button}
          titleStyle={styles.title}
          onPress={() => this.props.navigation.navigate("LoginScreen")}
        />
      </SafeAreaView>
    );
  }
}

export default withNavigation(BurgerMenu);
