Flutter pan/zoom via gesture or function

Question

My goal is to have a container of some sort, that I can zoom and pan via gestures, but also need to be able to zoom and pan to a specific location in the container via a button. I've tried all sorts of combinations of GestureDetector's mixed with Matrix4Transform and MatrixGestureDetector but am not having any luck allowing both hand and function initiated gestures to work together. Does anyone have something like this already working, and if so could you share any hints? Thanks

Take a look at this package: photo_view .
