🎯 Basic Usage

import React from 'react';
import { LocationAutocomplete } from '@pragadanaveen/react-native-location-autocomplete';

const MyComponent = () => {
  const handleLocationSelected = (location) => {
    console.log('Selected location:', location);
    // location object contains: { address, latitude, longitude, placeId, details }
  };

  return (
    <LocationAutocomplete
      apiKey="YOUR_GOOGLE_PLACES_API_KEY"
      onLocationSelected={handleLocationSelected}
      enableCurrentLocation={true}
      enableRecentSearches={true}
      filterCitiesOnly={true}
      style={{ margin: 16 }}
    />
  );
};

💰 API Cost Optimization

Your package includes advanced optimizations that significantly reduce Google Places API costs:

Smart Caching System

<LocationAutocomplete
  enableCaching={true}        // Cache responses for 5 minutes
  cacheTimeout={300000}       // Customizable cache duration
  maxCacheSize={100}          // Limit memory usage
/>

Request Coalescing

<LocationAutocomplete
  enableRequestCoalescing={true}  // Prevent duplicate requests
  // If user types "Mumbai" quickly, only 1 API call is made
/>

Skip Unnecessary Details Calls

<LocationAutocomplete
  skipDetailsForPredefined={true}  // Don't call details API for predefined places
  predefinedPlaces={[
    { description: 'Home', latitude: 19.0760, longitude: 72.8777 },
    { description: 'Office', latitude: 19.0896, longitude: 72.8656 }
  ]}
/>

Cost Comparison

Typical Usage Scenario: User types "Mumbai" (6 characters)

| Package | API Calls | Cost Impact | |---------|-----------|-------------| | react-native-google-places-autocomplete | 6 autocomplete + 1 details = 7 calls | Higher cost | | Your Package (optimized) | 1 autocomplete + 1 details = 2 calls | 71% cost reduction |

With Caching: Subsequent searches for "Mumbai" = 0 additional calls for 5 minutes!

🎨 Advanced Loading States

  apiKey="YOUR_API_KEY"
  onLocationSelected={handleLocationSelected}
  loadingRows={4}
  useShimmer={true}

Custom Loading Component

const CustomLoader = () => (
  <View style={{ padding: 20, alignItems: 'center' }}>
    <ActivityIndicator size="large" color="#007AFF" />
    <Text style={{ marginTop: 10, color: '#666' }}>
      Finding amazing places...
    </Text>
  </View>
);

    <Icon name="location" size={20} />
    <Text style={customStyles.text}>{data.description}</Text>

🌍 Location Data Structure

The onLocationSelected callback receives a comprehensive location object:

{
  address: "Mumbai, Maharashtra, India",
  latitude: 19.0760,
  longitude: 72.8777,
  placeId: "ChIJwe1EZjDG5zsRaYxkjY_tpF0",
  details: {
    // Full Google Places API response
    geometry: { location: { lat: 19.0760, lng: 72.8777 } },
    address_components: [...],
    formatted_address: "Mumbai, Maharashtra, India",
    // ... other place details
  }
}

🚀 Performance Tips

1. Use debouncing: Adjust debounceMs based on your needs (300-500ms recommended)
2. Set minimum length: Use minLength to avoid unnecessary API calls
3. Implement caching: Cache recent results to reduce API usage
4. Use country restrictions: Limit search scope with countryCode
5. Optimize rendering: Use renderRow for complex custom layouts

🔐 API Key Setup

1. Go to Google Cloud Console
2. Create a new project or select existing
3. Enable these APIs:
   • Places API
   • Geocoding API (for reverse geocoding)
4. Create credentials (API Key)
5. Restrict the key to your app's bundle ID/package name
