How to Fix JSX expressions must have one parent element Error in React Native

Understanding the Error

The critical problem lies in how JSX elements are nested within a component. JSX expressions must be enclosed within a single parent element. If they are not, React Native will throw this error to indicate improper structure, making element rendering impossible.

Example of the Error

Consider the following incorrect JSX structure:

Here, the <Text> and <Image> components are not wrapped within a single parent element, leading to the error.

How to Fix the Error

To resolve this issue, simply wrap all JSX elements within a single parent element such as a <View>. This ensures that the structure is correct and the error is eliminated.

Below is the corrected version of the JSX structure:

Alternatively, if you want to avoid an extra wrapper, you can use React Fragments, which do not render any additional DOM elements.
