nit: should this be added to toString?

What does "pointer" refer to in the doc? Shouldn't a scale gesture have 2 pointers? From the implementation, it should be the position change of the focal point?

Thanks for this, I should have waited for your review. You already saw my new PR but for the record it's at #85718.

The doc says delta will be in the coordinate space of the event receiver but here it looks like these 2 are pre-transformed (global) coordinates (because there's a localFocalPoint that has a different value)?

ScaleUpdateDetails is supposed to be a superset of DragUpdateDetails, but it is missing the
deltaparam. This PRs adds it.Closes #43833
