The method fails to deal correctly with LatLng wrap arounds. A more
correct version would probably look more like:
void pad(double bufferRatio) {
final heightBuffer = (_sw!.latitude - _ne!.latitude).abs() * bufferRatio;
final widthBuffer = (_sw!.longitude - _ne!.longitude).abs() * bufferRatio;
final point1 = LatLng((90 + _sw!.latitude - heightBuffer) % 180 - 90,
(180 + _sw!.longitude - widthBuffer) % 360 - 180);
final point2 = LatLng((90 + _ne!.latitude + heightBuffer) % 180 - 90,
(180 + _ne!.longitude + widthBuffer) % 360 - 180);
final newBounds = LatLngBounds(point1, point2);
_sw = newBounds.southWest;
_ne = newBounds.northEast;
}
On a tangent, it probably should be a factory rather than a mutable
method and the `bufferRatio` parameter is hard to use correctly. For
example, bufferRatio = 0.5 would increase the bounds to 4 times its
original size.

Any thoughts on deleting already broken code? |

Hey @ignatz, sorry for the massive delay. I'll take a look tommorrow. |

Naively, grab above version and provide it as a function or extension on latlngbounds |

A similar method of the same name was removed in fleaflet#1427. This method simply expands the LatLngBounds coordinates by latitude and longitude constants. Checks to ensure the adjustment remains "in-bounds" is performed, similar to the extend and extendBounds methods.
