FlLine constructor

const FlLine({
  1. Color? color,
  2. Gradient? gradient,
  3. double strokeWidth = 2,
  4. List<int>? dashArray,
})

Renders a line, color it by color, thickness is defined by strokeWidth, and if you want to have dashed line, you should fill dashArray, it is a circular array of dash offsets and lengths. For example, the array [5, 10] would result in dashes 5 pixels long followed by blank spaces 10 pixels long.

Implementation

const FlLine({
  Color? color,
  this.gradient,
  this.strokeWidth = 2,
  this.dashArray,
}) : color = color ??
          ((color == null && gradient == null) ? Colors.black : null);
