While developing the Flutter, you might have added the API calls or some other operations that wait for the data to get loaded before it appears on the screen. In such scenarios, you might have added the circular progress indicator in your app. It’s a way of letting users know about something is happening in the background. But sometimes you may also want to change the color of the circular progress indicator. So in this tutorial, we’ll see how you can change circular progress indicator color in Flutter.
Here’s what we’ll cover:

- How to change circular progress indicator color in Flutter
- Globally changing circular progress indicator color
When you add the CircularProgressIndicator to your page, you’ll notice that it appears in a color that you have set as the primarySwatch inside the theme. For example, if it’s blue then you’ll see blue color for the circular progress indicator. In most cases, you may want to change this default color to the color given by your designer.
How to change circular progress indicator color in Flutter

Step 4: Inside the AlwaysStoppedAnimation(), add the
color of your choice.
Step 5: (Optional) To change the background color of the CircularProgressIndicator you can add the

seedColor parameter and assign the
color and see if the color of the circular progress indicator matches your design.
Step 4: If not, add one more parameter called
primary and assign the
color of your choice.
MaterialApp( title: 'Flutter Demo', theme: ThemeData( primarySwatch: Colors.blue, colorScheme: ColorScheme.fromSeed( seedColor: Colors.greenAccent, primary: Colors.greenAccent, //<-- SEE HERE ), ), home: CircularProgressColorDemo(), ); ------ CircularProgressIndicator(),
In this tutorial, we learned how to the with practical examples. We first saw the problem with adding the CircularProgressIndicator as it is and then saw the way to change the color.
