TypeError: undefined is not an object (evaluating ‘_reactNative.Text.propTypes.style’) Solved

If you are developing a React Native application, you may encounter the following error: TypeError: undefined is not an object (evaluating ‘_reactNative.Text.propTypes.style’). This error typically occurs when you are trying to access a style property that is not defined or is undefined.

Causes of the Error

The error can occur due to various reasons, such as:

• Trying to access a style property that is not defined in the component
• Passing an undefined style object to a component
• Using an incorrect syntax when defining styles

Solutions

To solve the TypeError: undefined is not an object (evaluating ‘_reactNative.Text.propTypes.style’) error, you can follow these steps:

1. Check the component where the error is occurring and make sure that the style property is defined and not undefined.
2. If you are passing a style object to a component, ensure that the object is not undefined. You can use conditional rendering to handle undefined style objects.
3. Double-check the syntax of your style definitions. Make sure that you are using the correct syntax for defining styles in your React Native components.

Example

Here is an example of how you can handle undefined style objects in your React Native code:

      
      import React from 'react';
      import { View, Text, StyleSheet } from 'react-native';

      const CustomComponent = ({ style }) => {
        const defaultStyle = {
          fontSize: 16,
          color: 'black',
        };

        return (
          
            Hello, World!
          
        );
      };

      const styles = StyleSheet.create({
        // Define other styles here
      });

      export default CustomComponent;
      
    

Conclusion

The TypeError: undefined is not an object (evaluating ‘_reactNative.Text.propTypes.style’) error can be problematic, but it can be easily solved by checking for undefined style properties and handling them appropriately in your React Native components.
