I am trying to implement an image uploader into my app. Nonetheless, I keep getting the following error: Text strings must be rendered within a component.
All other files are working properly as they remain independent from this part of the app.
//fcard.js
import React, { useState } from 'react';
import { StyleSheet, Text, View, TouchableOpacity, Image } from 'react-native';
import ImagePicker from 'react-native-image-picker';
const Flcard = () => {
const [resourcePath, setResourcePath] = useState({});
const selectFile = () => {
var options = {
title: 'Select Image',
customButtons: [
{
name: 'customOptionKey',
title: 'Choose file from Custom Option',
},
],
storageOptions: {
skipBackup: true,
path: 'images',
},
};
ImagePicker.showImagePicker(options, res => {
console.log('Response = ', res);
if (res.didCancel) {
console.log('User cancelled image picker');
} else if (res.error) {
console.log('ImagePicker Error: ', res.error);
} else if (res.customButton) {
console.log('User tapped custom button: ', res.customButton);
alert(res.customButton);
} else {
setResourcePath(res);
}
});
};
return (
<View style={styles.container}>
<View style={styles.container}>
<Image
source={{
uri: 'data:image/jpeg;base64,' + resourcePath.data,
}}
style={{ width: 100, height: 100 }}
/>
<Image
source={{ uri: resourcePath.uri }}
style={{ width: 200, height: 200 }}
/>
<Text style={{ alignItems: 'center' }}>{resourcePath.uri}</Text>
<TouchableOpacity onPress={selectFile} style={styles.button}>
<Text style={styles.buttonText}>Select File</Text>
</TouchableOpacity>
</View>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 30,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: '#fff',
},
button: {
width: 250,
height: 60,
backgroundColor: '#3740ff',
alignItems: 'center',
justifyContent: 'center',
borderRadius: 4,
marginBottom: 12,
},
buttonText: {
textAlign: 'center',
fontSize: 15,
color: '#fff',
},
});
export default Flcard;
// Flashcards.js
import React, { useState } from 'react';
import { View, Text, StyleSheet, TouchableOpacity} from 'react-native';
import { Ionicons } from '@expo/vector-icons';
import Flcard from '../fcard';
const Flashcards = ({ route }) => {
const [showElements, setShowElements] = useState(true);
const handleTouch = () => {
setShowElements(!showElements);
};
const { task } = route.params;
const [items, setItems] = useState([]);
const handleAddItem = () => {
// Add a new item to the list
const newItem = {
id: Date.now(),
text: 'New Item',
};
setItems([...items, newItem]);
};
return (
<View style={styles.container}>
{showElements ? (
<>
<TouchableOpacity onPress={handleAddItem} style={styles.addButton}>
<Ionicons name="ios-add" size={30} color="#fff" />
</TouchableOpacity>
<View style={styles.itemList}>
{items.map((item) => (
<TouchableOpacity key={item.id} style={styles.item} onPress={handleTouch}>
<Text>{item.text}</Text>
</TouchableOpacity>
))}
</View>
<Text style={styles.title}>{task}</Text>
{/* Other task details */}
</> ) : (
<>
<Flcard/>
</>
)}
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
},
title: {
fontSize: 24,
fontWeight: 'bold',
}, addButton: {
position: 'absolute',
top: 10,
left: 10,
zIndex: 999,
backgroundColor: '#000',
padding: 10,
borderRadius: 15,
},
itemList: {
marginTop: 50,
},
item: {
padding: 10,
borderBottomWidth: 1,
borderBottomColor: '#ccc',
},
});
export default Flashcards;
I tried deleting all the elements in the return statement of the fcard.js, keeping only the View component. However, I get the same issue.

Does
item.text
always have a value? Null or [] will safely render an empty component / space whereas I believe undefined will give you this error.I have tested your code. its working fine. just clear cache of with the command
npx react-native start ---reset-cache
. Some time the error is cached thats why it thorowing the error. or restart your system .
