How can I use TypeScript to define props for custom React Native components

1. Define the Props Interface:
- Create an interface to define the props for your custom component. This interface should include all the properties that your component will accept.

2. Use the Interface in Your Component:
- Use the props interface in your component definition. This ensures that TypeScript checks for the correct types of props being passed to your component.

Here is an example of how you can define and use props in a custom React Native component using TypeScript:

typescript
// customtext.ts
import React from 'react';
import { View, Text } from 'react-native';

interface Props {
  text: string;
  color: string;
  fontWeight: string;
}

const CustomText: React.FC<Props> = ({ text, color, fontWeight }) => {
  return (
    <View>
      <Text style={{ color, fontWeight, fontSize: 20 }}>
        {text}
      </Text>
    </View>
  );
};

export default CustomText;

Example Usage

typescript
  import React from 'react';
  import { View, StyleSheet } from 'react-native';
  import CustomText from './customtext';

  const App = () => {
    return (
      <View style={styles.container}>
        <CustomText text="Hello, World!" color="red" fontWeight="bold" />
      </View>
    );
  };

  const styles = StyleSheet.create({
    container: {
      flex: 1,
      justifyContent: 'center',
      alignItems: 'center',
    },
  });

  export default App;
