If you’re a Flutter developer building dashboards, analytics apps, or reporting tools, and you often deal with large datasets, you’ll know how tricky it can be to find a charting library that balances ease of use, performance, and flexibility.
That’s the gap I tried to solve when building Cristalyse. Here are 7 reasons you might find it useful:
1. Simple Grammar of Graphics
Cristalyse uses a grammar of graphics approach (inspired by ggplot). Instead of wiring endless widget configs, you describe what you want:
CristalyseChart()
.data(data)
.mapping(x: 'month', y: 'revenue', color: 'region')
.geomBar()
.theme(ChartTheme.cyberpunk())
.build();
Readable, customizable, and much closer to how you think about data.
2. Handles 50k+ Data Points Smoothly
Performance was a big focus. Cristalyse stays responsive even when plotting tens of thousands of data points, so you don’t have to cut corners.
3. Built-In Animations and Interactivity
You don’t need extra packages to get the basics right:
- Smooth animations
- Interactive Panning
- Tooltips, legends, theming
4. 15+ Chart Types
Bar, line, area, scatter, bubble, heatmaps, grouped bars, stacked bars — and each one is customizable.
5. Advanced Features When You Need Them
Multiple axes, categorical coloring, bubble sizing, heatmaps. These are supported natively, so you won’t have to hack your way around them.
6. Open Source Under MIT
Cristalyse is open source under the MIT license, so you can use it freely in commercial apps without restrictions.
7. Clear, Practical Documentation
The docs are written to be straightforward and example-driven, so you can get comfortable in a short amount of time without a steep learning curve.

- ⚡ GPU-Accelerated Performance - Handle large datasets without breaking a sweat
- 🎯 Flutter-First Design - Seamlessly integrates with your existing Flutter apps
- 📊 Dual Y-Axis Support -…
If you run into questions, there’s a space on GitHub Discussions where you can ask. I’m actively maintaining Cristalyse, so feedback and issues are always welcome.
Closing Thoughts
Cristalyse is still evolving, but it’s already usable for real dashboards and applications. If you’ve been struggling with performance or complexity in other libraries, this might give you a smoother experience.
