As an alternative to MatrixGestureDetector, you can use the photo_view package: https://pub.dev/packages/photo_view

It has good limiting of the screen constraints so you can't drag the child off-screen, a bounce effect when hitting min/max size, and many other options.

It can be used with a custom child like this:

PhotoView.customChild(
    child: 
)
