clamp method

double clamp(double zoom)

Clamps zoom into this config's range.

Implementation

double clamp(double zoom) {
  // The constructor's `assert(max >= min)` is stripped from release builds,
  // where a backwards range would otherwise make `clamp` return NaN on every
  // call. Guard it here so the misconfiguration fails loudly at its source.
  if (min > max) {
    throw StateError(
      'SagaMapZoomConfig has min ($min) greater than max ($max)',
    );
  }
  return zoom.clamp(min, max);
}
