Then run:
flutter pub get

🚀 Usage
Import the package:

import 'package:reward_progress_bar/reward_progress_bar.dart';

1. Basic Usage (Default Icons)
The simplest way to use the package. It uses default check icons.
CardPoints(
  currentPoints: 45,
  milestones: const [0, 30, 60, 90],
)

2. Full Customization (Gamification Style)
Example with custom icons (Stars), labels, colors, and tap interaction.

CardPoints(
  currentPoints: 75,
  milestones: const [0, 50, 100, 150, 200],
  labels: const ["Start", "Bronze", "Silver", "Gold", "Diamond"],
  // Customization
  progressColor: Colors.amber,
  trackColor: Colors.amber.withValues(alpha: 0.2), // Updated for Flutter 3.22+
  iconSize: 30,
  lineHeight: 8, // Control line thickness
  animationDuration: const Duration(milliseconds: 800), // Slower animation
  animationCurve: Curves.bounceOut, // Bouncy effect
  labelStyle: const TextStyle(
    color: Colors.amber,
    fontWeight: FontWeight.bold,
    fontSize: 12,
  ),
  // Custom Icons (You can use SvgPicture here)
  completedIcon: const Icon(Icons.star, color: Colors.amber, size: 30),
  pendingIcon: Icon(Icons.star_border, color: Colors.amber.shade200, size: 30),
  onMilestoneTap: (index) {
    print("Clicked on milestone index: $index");
  },
)


3. Using SVG Assets
To use SVGs, simply pass SvgPicture.asset to the icon properties:

CardPoints(
  currentPoints: 60,
  milestones: const [0, 50, 100],
  completedIcon: SvgPicture.asset("assets/check.svg", width: 24, height: 24),
  pendingIcon: SvgPicture.asset("assets/lock.svg", width: 24, height: 24),
)
