new_loading_indicator #

A fork of the loading_indicator package, providing a rich collection of loading animations for Flutter applications. The original package is unmaintained, has outdated dependencies, poor documentation, and was written without a single test. This fork aims to:

• Modernize the codebase for compatibility with the latest Flutter/Dart SDK versions
• Update outdated dependencies
• Add comprehensive test coverage
• Provide detailed documentation for maintainability
• Ensure ongoing maintenance and active development

Visit the example on GitLab Pages for a live demo.

Installation #

Add this to your package's pubspec.yaml file:

dependencies:
  new_loading_indicator: ^latest_version

Usage #

import 'package:new_loading_indicator/new_loading_indicator.dart';

// Basic usage
LoadingIndicator(
  indicatorType: Indicator.ballPulse, // Choose your animation
  colors: const [Colors.white],        // Customize colors
  strokeWidth: 2,                      // Customize the stroke width
  backgroundColor: Colors.black,       // Optional background color
);

// With custom size
SizedBox(
  width: 100,
  height: 100,
  child: LoadingIndicator(
    indicatorType: Indicator.ballSpinFadeLoader,
    colors: const [Colors.white],
  ),
);

Available Indicators #

The package includes 34 indicators, each customizable to match your app's design:

• Ball Pulse
• Ball Grid Pulse
• Ball Clip Rotate
• Square Spin
• Ball Clip Rotate Pulse
• Ball Clip Rotate Multiple
• Ball Pulse Rise
• Ball Rotate
• Cube Transition
• Ball Zig Zag

• Ball Scale
• Line Scale
• Line Scale Party
• Ball Scale Multiple
• Ball Pulse Sync
• Ball Beat

• Line Scale Pulse Out Rapid
• Ball Scale Ripple
• Ball Scale Ripple Multiple
• Ball Spin Fade Loader
• Line Spin Fade Loader
• Triangle Skew Spin
• Pacman
• Ball Grid Beat
• Semi Circle Spin
• Ball Rotate Chase
• Orbit
• Audio Equalizer
• Circle Stroke Spin

Pausing #

Set pause: true to freeze an indicator in place; set it back to false to resume from the same frame.

LoadingIndicator(
  indicatorType: Indicator.ballPulse,
  pause: isPaused,
);

Indicator.circleStrokeSpin wraps Flutter's CircularProgressIndicator and can't be paused.

Colors #

When colors is null or empty, the indicator uses Theme.of(context).colorScheme.primary. Indicators with several shapes cycle through the list, so [Colors.red, Colors.blue] alternates the two.
