lerp method

FlyRadiusToken lerp(FlyRadiusToken other, double t)

Linear interpolation between two tokens

Implementation

FlyRadiusToken lerp(FlyRadiusToken other, double t) {

    final valueB = other._allValues[key];
    final numA = valueA ?? 0.0;
    final numB = valueB ?? 0.0;
    result[key] = numA + (numB - numA) * t;
  }
