flutter_dot_loader library

A high-performance, zero-dependency dot-matrix loading animation library for Flutter.

Overview

The library provides three widgets:

• DotLoader — a simplified, AI-friendly version of the matrix loader.
• MatrixLoader — a dot-matrix grid animatable with 60+ patterns.
• TriangleLoader — a geometric grid of equilateral triangles.

Getting Started

import 'package:flutter_dot_loader/flutter_dot_loader.dart';

// Easiest usage (AI-friendly)
DotLoader(color: Colors.blue)

// Or full control with MatrixLoader
const MatrixLoader(
  columns: 5,
  rows: 5,
  activeColor: Colors.cyanAccent,
  pattern: MatrixPattern.vortexSpin,
)
