How to Display Rating Numbers Alongside Stars in Google Places API with Flutter

When developing applications with Flutter that utilize the Google Places API, it’s common to display visual representations of ratings. You may already use RatingBarIndicator to show star ratings but might encounter the need to also display the numeric rating next to these stars. This guide will guide you step-by-step on how to extract and display that numeric rating effectively alongside the stars.

Understanding the Problem

The RatingBarIndicator widget is a convenient way to visualize ratings with stars. However, you might find it lacking when it comes to displaying actual rating numbers. So, how do we combine star ratings with their corresponding numeric values? Let’s break down the solution.

Solution Overview

We’ll be using a combination of the RatingBarIndicator and a simple Text widget to achieve this. The following sections will present a clear path to displaying the rating number next to the star ratings drawn from the Google Places API.

Step 1: Extract the Rating from the API

Firstly, ensure you have set up your data class correctly to extract the rating information from the JSON response provided by the Google Places API. Here’s how your Place class might look:

Here, we ensure we capture the rating and user_rating_total, which can be useful for later display.

Step 2: Display the Rating with the Stars

When it’s time to show the data in your UI, you will be using ListView.builder to create a widget for each place. Here’s a code snippet that shows how to include the rating stars followed by the numeric rating:

Key Points to Implement

Extract Rating: Ensure the rating data is correctly parsed and made available in your Place class.

Arrange Widgets: Nest the RatingBarIndicator within a Row alongside a Text widget to show the numeric rating.

Style as Needed: Use padding or styling options to seamlessly blend the numeric rating with the star ratings for better visual appeal.

Conclusion

Combining star ratings with their numeric representations can significantly enhance the user experience in your Flutter applications utilizing the Google Places API. By following the steps outlined above, you can effectively display the rating numbers next to stars, thus providing comprehensive feedback to your users.

Now, you can take your application to the next level by making rating information not only visually appealing but also informative!
