React Native Smart dimension

react-native-smart-dimension is a lightweight and flexible library for handling responsive design in React Native applications. It provides hooks to manage device types, screen dimension, and scalable layouts for various screen sizes, including mobile and tablet devices.

Installation

You can install the library using npm or yarn:

npm install react-native-smart-dimension

yarn add react-native-smart-dimension

Features

Detects device type (mobile or tablet)
Provides responsive height, width, and font scaling utilities
Listens for screen dimension changes in real-time
Supports percentage-based and font scaling calculations
Optimized for React Native projects

Usage

1. Detect Device Type

import { useDeviceType } from "react-native-smart-dimension";

const { isTablet, platform } = useDeviceType();
console.log(`Device Type: ${isTablet ? "Tablet" : "Mobile"}, Platform: ${platform}`);

2. Listen to Screen Dimension Changes

import { usedimensionListener } from "react-native-smart-dimension";

const { screen, window } = usedimensionListener();
console.log("Window dimension:", window);
console.log("Screen dimension:", screen);

3. Responsive Height & Width

import { useResponsiveHeight, useResponsiveWidth } from "react-native-smart-dimension";

const height = useResponsiveHeight(50); // 50% of window height
const width = useResponsiveWidth(80); // 80% of window width

4. Responsive Font Size

import { useResponsiveFontSize } from "react-native-smart-dimension";

const fontSize = useResponsiveFontSize(2); // Scales based on screen size

5. Table View Layout Helper

import { useTableView } from "react-native-smart-dimension";

const { columnWidth, gap } = useTableView(3, 5); // 3 columns with 5% gap
