Learn how to fix: "React.Children.only expected to receive a single React element child" error when putting <Image> and <TouchableHighlight> in a <View>.
📋 Table of Contents
The "React.Children.only expected to receive a single React element child" error occurs when using nested components in React Native, specifically with Image and TouchableHighlight components within a View.
This issue affects developers who are trying to render complex user interfaces with multiple components, but haven't properly configured their children.
🔍 Why This Happens
- The primary cause of this error is that the Image component is being used as a child of the TouchableHighlight component, which expects only one React element child. This can be due to a misunderstanding of how React Native handles nested components.
- Another possible reason for this issue could be if there are other components inside the TouchableHighlight component, causing it to receive multiple children instead of just one.
✅ Best Solutions to Fix It

- Step 11: import { View } from 'react-native';
- Step 12: import ImageWrapper from './ImageWrapper';
- Step 13: export default function MyComponent() {
- Step 14: return (
- Step 15:
- Step 16:
- Step 17:
- Step 18:;

- Step 1: Use the native Image component instead of the React Native Image component, and pass the resizeMode prop to it:
- Step 2: javascript
- Step 3: import React from 'react';
- Step 4: import { View } from 'react-native';
- Step 5: import { Image } from 'react-native';
- Step 6: export default function MyComponent() {
- Step 7: return (
- Step 8:
