Integrating Google Places Autocomplete in Flutter Text Form Field

If you've ever searched for addresses or locations in a mobile app, you're likely familiar with Google Places Autocomplete. This feature simplifies the process of finding places by suggesting addresses as you type. As a Flutter developer, you might want to incorporate this functionality into a TextFormField in your application. But how can you do this effectively? In this guide, we'll explore how to implement Google Places Autocomplete in a Flutter TextFormField and ensure that selected locations populate the field correctly.

Understanding the Problem

You may have encountered a scenario where tapping on a TextFormField opens up the autocomplete suggestions using the Google Places API, but after selecting a suggestion, the text does not populate the field. This can be frustrating and lead to a poor user experience. The good news is that fixing this issue is straightforward!

Step-by-Step Solution

To successfully integrate Google Places Autocomplete in your Flutter app, follow these steps:

Step 1: Set Up Your Text Form Field
