How to Make a Non-Clickable Rating Bar in Flutter

If you're developing a Flutter application, you might encounter situations where you want to allow users to give feedback through a rating bar but also want to disable further interactions after they've submitted their rating. This is a common requirement, especially in feedback mechanisms where repeated ratings can skew results or confuse users. In this guide, we will explore how to make a rating bar non-clickable in Flutter.

Understanding the Rating Bar Widget

The Flutter Rating Bar widget is a convenient way to allow users to rate items, events, or experiences on a scale. By default, users can click on the stars to give their rating, but there are instances when you may want to lock this functionality after they've already provided their input.

The Need for a Non-Clickable Rating Bar

User Feedback: Often, applications need to capture user feedback through ratings.

Action Limitation: To prevent users from changing their minds or leaving multiple ratings for the same experience.

Data Integrity: Maintaining the accuracy of data collected through user feedback.

How to Make the Rating Bar Non-Clickable

To make the Flutter Rating Bar non-clickable, you can easily modify its properties. Here’s how you can implement this:

Step 1: Define the Rating Bar

The first step involves defining your Rating Bar widget within your Flutter application. Here's a sample structure:

Key Takeaways

Simple Solution: Adding the ignoreGestures: true line renders your rating bar non-clickable, allowing only for display purposes after feedback submission.

Maintains User Experience: This functionality helps in managing user expectations, ensuring they can only provide feedback once, thus improving the quality of data collected.

Customizable: You can continue to customize your ratings bar with images and other features without compromising on the non-clickable aspect.

By following the steps outlined above, you can easily implement a non-clickable rating bar in your Flutter app, allowing for a more controlled feedback process. Enjoy coding!
