To retrieve street, city, state, and zip code information from the Google Places API, you'll need to make a request to the API and parse the response. Here's a general outline of the steps to achieve this:

  • Obtain API Key:
    • Go to the Google Cloud Console (https://console.cloud.google.com/).
    • Create a new project or select an existing one.
    • Enable the "Places API" for your project and generate an API key.
  • Make an API Request:
    • Use the generated API key to make a request to the Google Places API.
    • You can use the "Place Search" or "Place Details" request to retrieve information about a place. For this example, we'll use "Place Details."
  • Parse the Response:
    • Once you receive the API response, parse it to extract the required information, including street, city, state, and zip code.

Here's a Python example using the requests library to make an API request and parse the response:

To retrieve street, city, state, and zip code information from the Google Places API in a Flutter app, you can use the http package to make API requests and parse the JSON response. Here's an example Flutter code snippet to achieve this:

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:http/http.dart as http;

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String street = '';
  String city = '';
  String state = '';
  String zipCode = '';

  // Replace with your Google Places API key
  final String apiKey = 'YOUR_API_KEY';

  Future<void> fetchPlaceDetails(String placeId) async {
    final url =
        'https://maps.googleapis.com/maps/api/place/details/json?place_id=$placeId&fields=address_components&key=$apiKey';

    final response = await http.get(Uri.parse(url));

    if (response.statusCode == 200) {
      final data = json.decode(response.body);

      final addressComponents = data['result']['address_components'];

      for (final component in addressComponents) {
        final types = List<String>.from(component['types']);

        if (types.contains('street_number') || types.contains('route')) {
          street = component['long_name'];
        } else if (types.contains('locality')) {
          city = component['long_name'];
        } else if (types.contains('administrative_area_level_1')) {
          state = component['short_name'];
        } else if (types.contains('postal_code')) {
          zipCode = component['long_name'];
        }
      }

      setState(() {});
    } else {
      throw Exception('Failed to load place details');
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Place Details Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              ElevatedButton(
                onPressed: () {
                  // Replace 'YOUR_PLACE_ID' with the actual place ID you want to retrieve details for
                  fetchPlaceDetails('YOUR_PLACE_ID');
                },
                child: Text('Get Place Details'),
              ),
              Text('Street: $street'),
              Text('City: $city'),
              Text('State: $state'),
              Text('ZIP Code: $zipCode'),
            ],
          ),
        ),
      ),
    );
  }
}


Make sure to replace 'YOUR_API_KEY' with your actual Google Places API key and 'YOUR_PLACE_ID' with the place ID for the location where you want to retrieve details. This Flutter app provides a basic interface with a button to trigger the API request and displays the retrieved address components on the screen.

Conclusion

Harnessing the capabilities of the Google Places API empowers developers to enhance their applications with precise location details. By following the steps outlined in this guide, you can seamlessly integrate street, city, state, and zip code retrieval into your projects, enriching the user experience and unlocking new possibilities for location-based functionality.
