What are PropTypes in React Native?

What are PropTypes in React Native?

PropTypes are a way to validate the props passed to a component in React Native, ensuring they are of the correct type.

How do I use PropTypes in my React Native project?

You can use PropTypes by importing it from 'prop-types' and defining the expected types for your component's props.

Can you give me an example of using PropTypes?

Sure! Here's a simple example:

import PropTypes from 'prop-types';

const MyComponent = ({ name, age }) => {
  return <Text>{`Name: ${name}, Age: ${age}`}</Text>;
};

MyComponent.propTypes = {
  name: PropTypes.string.isRequired,
  age: PropTypes.number,
};

What happens if I don't use PropTypes?

If you don't use PropTypes, you won't have runtime validation for your props, which can lead to bugs if incorrect types are passed.
