fl_chart is a charting library for Flutter that focuses on expressive, highly customizable data visualizations with smooth animations. It offers a broad set of chart types—line, bar, pie, scatter, and radar—each exposed through clear data/option models rather than imperative drawing. Interactive features like touch handling, tooltips, selection/highlighting, and panning help apps present insights rather than static images. The package pays special attention to aesthetics, with options for gradients, curved lines, stacked bars, rounded corners, custom tick formats, and flexible legends. Because it’s built on Flutter’s rendering primitives, it scales crisply on any device and adapts well to layout constraints. Its API is designed so teams can start simple and progressively layer in formatting, interactions, and performance tweaks as dashboards grow in complexity.
