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.
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>
)
}
}
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
?
Interface NavigatorThe state and the identity of the user agent. It allows scripts to query it and to register themselves to carry on some activities.
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);
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
