spinToSegment method

void spinToSegment({ required WheelSegment selectedSegment, required List<WheelSegment> segments, })

Implementation

}) {
  // ========================================
  // VALIDATION
  // ========================================

  // ========================================
  // CALCULATE TOTAL WEIGHT
  // ========================================
  final totalWeight = _calculateTotalWeight(segments);

  // ========================================
  // CALCULATE TARGET ANGLE
  // ========================================
  final targetAngle = _calculateTargetAngle(

  // ========================================
  // ADD RANDOM OFFSET
  // ========================================
