forZoomlevel method

@override RenderinstructionPolylineText forZoomlevel(int zoomlevel, int level)

Creates a copy of itself with the data needed for the given zoomlevel. Note that this should only be called from Rendertheme and NOT from RenderthemeZoomlevel

Implementation

@override
RenderinstructionPolylineText forZoomlevel(int zoomlevel, int level) {
  RenderinstructionPolylineText renderinstruction = RenderinstructionPolylineText(level)
    ..renderinstructionScale(this, zoomlevel)
    ..baseSrcMixinScale(this, zoomlevel)
    ..textSrcMixinScale(this, zoomlevel)
    ..strokeSrcMixinScale(this, zoomlevel)
    ..fillSrcMixinScale(this, zoomlevel)
    ..repeatSrcMixinScale(this, zoomlevel);
  renderinstruction.textKey = textKey;
  // we need the zoomlevel for calculating the position of the individual texts
  renderinstruction.zoomlevel = zoomlevel;
  return renderinstruction;
}
