TAM Chart

A customizable charting package for Flutter, supporting all platforms.

A powerful and easy-to-use Flutter library for creating and displaying animated charts representing Total Addressable Market (TAM) data.

✨ Features

• 🎯 Animated Charts: Smooth drawing animations with customizable duration.
• 🎨 Style Customization: Customize colors and text styles for each circle to match your app's theme.
• 🧭 Directional Animation Support: Circle drawing animation now respects the somPosition and direction values. For example, if somPosition is set to top, the animation begins and ends at the top. If it’s left, it starts and ends from the left.
• 📍Flexible Positioning: Position the SOM circle within the chart using predefined positions (top, bottom, left, right, center).
• 🔢 Readable Numeric Values: Large numbers are auto-formatted (e.g. 1500 → 1.5K, 1500000 → 1.5M).
• 💾 Chart Export (NEW): Easily export the chart as a PNG image and save it to disk or download in the browser
• Easy Integration: Seamlessly integrate the package into your Flutter project with minimal setup.
