GpsPointsCollection<GpsPoint> newEmpty({
  1. int? capacity,

Creates a collection of the same type as this, optionally with a starting capacity for children that support that.

Setting the capacity at the correct value can for huge lists with millions of items have a significant impact on the performance of filling the list.


GpsPointsCollection<GpsPoint> newEmpty({int? capacity}) {
  return GpcCompactGpsPoint()..capacity = capacity ?? 0;
