Quick Start

More examples will be added, but this will get you going in the meantime. The chart can be sized with a container or by passing in a Size object to the size named parameter.

Center(
  child: Container(
    width: 300,
    height: 300,
    child: SpiderChart(
      data: [
        7,
        5,
        10,
        7,
        4,
      ],
      maxValue: 10, // the maximum value that you want to represent (essentially sets the data scale of the chart)
      colors: <Color>[
        Colors.red,
        Colors.green,
        Colors.blue,
        Colors.yellow,
        Colors.indigo,
      ],
