getTileMatrixSetBounds method Null safety

Envelope getTileMatrixSetBounds()

Returns the tile matrix set bounds. The bounds are expressed in the same CRS as the entry, but they might differ in extent (if null, then the tile matrix bounds are supposed to be the same as the entry)


Envelope getTileMatrixSetBounds() {
  return tileMatrixSetBounds != null ? tileMatrixSetBounds! : bounds;
