Implementing styles from a constant file in React Native: A simple guide

In my file register.js, I have a UI component.

import CustomHeader from '../components/Header';
...
 static navigationOptions = ({navigation, navigation: { state } }) => {
        return {
            title: '',
            headerStyle: CustomHeader
        }
    };

I am attempting to create and utilize the CustomHeader style from another constant file.

 import { getStatusBarHeight } from "react-native-safearea-height";
 import { Platform } from 'react-native'; 

 var iosMarginTop = getStatusBarHeight(true);
 const headerStyle = ({backgroundColor = '#000'}) => {
    backgroundColor: backgroundColor,
    marginTop: Platform.OS == 'ios' ? iosMarginTop : 0
 }

 export default headerStyle;

How can I dynamically call the CustomHeader style and pass parameters for specific UI styles, such as backgroundColor? By default, if no parameter is passed, it will remain at the default value of "#000".

Answer №1

To enhance your code, make the following adjustments:

 const customizeHeader = ({bgColor}) => {
    backgroundColor: bgColor ? bgColor : "#000",
    marginTop: Platform.OS == 'ios' ? iosMarginTop : 0
 }
