Constructs a KnobController

Implementation

  this.maximum = 100,
  this.startAngle = 0,
  this.endAngle = 180,
  this.precision = 2,
})  : assert(maximum > minimum,
          'Maximum value must be greater than minimum value.'),
      assert(maximum >= initial && initial >= minimum,
          'Initial value must be between minimum and maximum values.'),
      super(KnobValue(
        current: initial,
        minimum: minimum,
        maximum: maximum,
        startAngle: startAngle,
        endAngle: endAngle,
