Hello Product Hunt community, I'm sharing Cristalyse because it addresses a real performance gap in Flutter data visualization. Key differentiators: Performance: Maintains 60fps with large datasets through direct Flutter rendering Flexibility: Grammar-of-graphics API enables complex visualizations without complexity Professional features: Built-in dual Y-axis, SVG export, and interactive tooltips The technical approach matters: instead of building complex widget hierarchies, Cristalyse uses CustomPainter for direct canvas rendering. This delivers native performance across mobile, web, and desktop. Use cases we're seeing: financial dashboards requiring smooth real-time updates, analytics platforms with large datasets, and cross-platform apps where consistent performance is critical. The library is production-ready and actively maintained. Documentation and examples available at docs.cristalyse.com Interested to hear feedback from other developers working on data-intensive Flutter applications.
