If you’re developing a Flutter application, chances are you’ve encountered scenarios where users need to wait for content to load. Instead of leaving them staring at a blank screen, why not entertain them with some engaging loading indicators? Enter Flutter Spinkit, a library that offers a delightful assortment of loading animations that can elevate the user experience. In this guide, we’ll explore how to set up and use Flutter Spinkit effectively.

How to Install Flutter Spinkit

To get started with Flutter Spinkit, you need to follow a simple installation process:

• Open your project’s pubspec.yaml file.
• Add the following dependency:

dependencies:
  flutter_spinkit: ^5.2.1

• Save the file and run the command flutter pub get in your terminal.

Importing Flutter Spinkit into Your Project

Now that you’ve installed Flutter Spinkit, it’s time to import it into your Dart files where you intend to use the animations:

import 'package:flutter_spinkit/flutter_spinkit.dart';

How to Use Flutter Spinkit

Imagine loading indicators like colorful dancers at a party pulling in guests with their fun moves. Flutter Spinkit offers various indicators, each with its own style and flair. Here’s how to implement some of these animated indicators:

1. Rotating Circle

const spinkit = SpinKitRotatingCircle(
  color: Colors.white,
  size: 50.0,
);

Think of this as a merry-go-round that keeps rotating, signaling that the app is busy processing.

2. Fading Circle

final spinkit = SpinKitFadingCircle(
  itemBuilder: (BuildContext context, int index) {
    return DecoratedBox(
      decoration: BoxDecoration(
        color: index.isEven ? Colors.red : Colors.green,
      ),
    );
  },
);

This acts like a fading light which gently appears and disappears, keeping the user interested.

3. Square Circle

final spinkit = SpinKitSquareCircle(
  color: Colors.white,
  size: 50.0,
  controller: AnimationController(
    vsync: this,
    duration: const Duration(milliseconds: 1200),
  ),
);

Visualize this as a square that smoothly transitions into a circle, playing with users’ perceptions.
