React Navigation, how to hide the back button title?

Question

I'm using React Native to build an Android and iOS application. I'm using react-navigation to navigate between screens.

The problem is that the navigation on iOS is different from the one in Android (image below). I want both of them to be like on Android, so how can I hide the 'Search cars' from iOS?

I've set the navigation options as follows:

Screen.navigationOptions = () => {

    const title = 'Search location';

    return {
        headerTitleStyle: {
            fontSize: 18,
            color: styles.headerTitle.color,
            paddingTop: 5,
            height: 40
        },
        headerStyle: {
            backgroundColor: '#fdfdfd'
        },
        title
    };
};

As of version 5, it is the option headerBackTitleVisible in screenOptions

Example of usage:

1. In Navigator

<Stack.Navigator
  screenOptions={{
    headerBackTitleVisible: false
  }}
>
  <Stack.Screen name="route-name" component={ScreenComponent} />
</Stack.Navigator>

2. In Screen

if you want only to hide in the single screen you can do this by setting the screenOptions on the screen component see below for example:

<Stack.Screen options={{headerBackTitleVisible: false}} name="route-name" component={ScreenComponent} />

3. In Screen Navigation Options

Screen.navigationOptions = ({ navigation }) => {
 headerTitle: 'Title',
 headerLeft: () =>
    <View>
      /* custom View here - back icon/back button text */
    </View
}

4. Common in navigator for all the screens

import { HeaderBackButton } from '@react-navigation/elements';

 <Stack.Navigator
            screenOptions={({ navigation }) => ({
                headerLeft: () => (
                    <HeaderBackButton
                        labelVisible={false}
                        tintColor={'#FFF'}
                        onPress={() => navigation.goBack()}
                    />
                )
            })}>

You need to set the headerBackTitleVisible: false to hide the back button title. It can be on a Screen's options, on a Navigator's screenOptions, or like in your case inside Screen.navigationOptions.

Screen.navigationOptions = () => {

    const title = 'Search location';

    return {
        headerBackTitleVisible: false, // all you needed
        headerTitleStyle: {
            fontSize: 18,
            color: styles.headerTitle.color,
            paddingTop: 5,
            height: 40
        },
        headerStyle: {
            backgroundColor: '#fdfdfd'
        },
        title
    };
};
