The Flutter Spline Chart resembles a line chart, but the difference between them is that instead of connecting the data points with straight lines, the data points are connected by smooth Bezier curves. You can create beautiful, animated, real-time and high-performance spline chart that also supports the interactive features such as zooming and panning, trackball, crosshair, tooltip and selection.
