Installation

First, install the package:

npm install @modhamanish/react-native-transformable-view
# or
yarn add @modhamanish/react-native-transformable-view

Peer Dependencies

Usage

Wrap your content with TransformableView to make it interactive.

import React, { useState } from 'react';
import { View, StyleSheet } from 'react-native';
import TransformableView from '@modhamanish/react-native-transformable-view';

const App = () => {
  const [selectedId, setSelectedId] = useState<string | null>(null);

  const handleSelect = (id: string) => {
    setSelectedId(id);
  };

  const handleDeselect = () => {
    setSelectedId(null);
  };

  const handleDelete = (id: string) => {
    console.log('Delete item:', id);
  };

  const handleCopy = (id: string) => {
    console.log('Copy item:', id);
  };

  return (
    <View style={styles.container}>
      <TransformableView
        id="item-1"
        isSelected={selectedId === 'item-1'}
        onSelect={handleSelect}
        onDeselect={handleDeselect}
        onDelete={handleDelete}
        onCopy={handleCopy}
        initialX={100}
        initialY={100}
        initialWidth={150}
        initialHeight={150}
      >
        <View style={styles.box}>
          {/* Your Content Here */}
        </View>
      </TransformableView>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#f0f0f0',
  },
  box: {
    flex: 1,
    backgroundColor: 'tomato',
