I think the word Read between the TouchableOpacity tags should be within Text tags.

CodePudding user response：

You can't add Text inside TouchableOpacity component Do this:

<TouchableOpacity style={styles.button} onPress={() => navigation.navigate('Document', {path})}>
     <Text>Read</Text>
</TouchableOpacity>

CodePudding user response：

Try Doing this same

<View style={styles.container}>
<View style={styles.square}>
    <Text style={styles.h1}>{item.title}</Text>
    <TouchableOpacity style={styles.button} onPress={() => navigation.navigate('Document', {path})}>
        <Text>Read</Text>
    </TouchableOpacity>
</View>
