2. Click on the “Create Credentials” button and select “OAuth API keys”.
3. Choose “Web API key” and click on the “Create” button.
4. Copy the API key, you’ll need it later.

Implementing Google Places Autocomplete in React Native

Now that we have our API key, let’s implement Google Places Autocomplete in our React Native app!

Step 1: Install the Required Packages

First, you need to install the required packages using npm or yarn:

npm install react-native-google-places-autocomplete

Step 2: Import the GooglePlacesAutocomplete Component

Next, import the GooglePlacesAutocomplete component in your React Native component:

import React, { useState } from 'react';
import { View, Text, TextInput } from 'react-native';
import GooglePlacesAutocomplete from 'react-native-google-places-autocomplete';

const App = () => {
  const [address, setAddress] = useState('');

  return (
    <View>
      <TextInput
        placeholder="Enter address"
        value={address}
        onChangeText={text => setAddress(text)}
      />
      <GooglePlacesAutocomplete
        placeholder="Enter address"
        minLength={2}
        autoFocus={true}
        returnKeyType={'search'}
        listViewDisplayed="auto"
        fetchDetails={true}
        renderDescription={row => row.description}
        onPress={(data, details) => {
          setAddress(data.description);
        }}
        query={{
          key: 'YOUR_API_KEY',
          language: 'en', // language of the results
          types: '(cities)', // default: 'geocode'
        }}
      />
    </View>
  );
};

export default App;

Step 3: Configure the GooglePlacesAutocomplete Component

Now, let’s configure the GooglePlacesAutocomplete component to show specific city addresses:

Property	Description
placeholder	The placeholder text for the input field.
minLength	The minimum number of characters required to trigger the autocomplete.
autoFocus	Whether the input field should be focused automatically.
returnKeyType	The return key type for the input field.
listViewDisplayed	Whether the autocomplete list should be displayed automatically.
fetchDetails	Whether to fetch additional details for the selected place.
renderDescription	A function to render the description of the selected place.
onPress	A function to handle the selection of a place.
query	An object with options for the autocomplete query.

Showing Specific City Addresses

To show specific city addresses, you can use the `types` property in the `query` object and set it to `(cities)`. This will restrict the autocomplete results to cities only.

query={{
  key: 'YOUR_API_KEY',
  language: 'en', // language of the results
  types: '(cities)', // default: 'geocode'
}}

Additionally, you can use the `components` property to filter the results by city or region:

query={{
  key: 'YOUR_API_KEY',
  language: 'en', // language of the results
  types: '(cities)', // default: 'geocode'
  components: [
    {
      component: 'country',
      types: ['country'],
    },
    {
      component: 'administrative_area_level_1',
      types: ['administrative_area_level_1'],
    },
    {
      component: 'locality',
      types: ['locality'],
    },
  ],
}}

Conclusion

And that’s it! You’ve successfully implemented Google Places Autocomplete in your React Native app and configured it to show specific city addresses. With this powerful tool, you can provide an amazing user experience and reduce friction in your app.

Remember to replace `YOUR_API_KEY` with your actual API key and adjust the configuration options to fit your app’s requirements.
