pinch_zoom

A widget based on Flutter's Interactive Viewer that makes picture pinch zoom, and return to its initial size and position when released.

This package offers Instagram based pinch zooming that feels more responsive than other similar packages.

The package is designed for zooming in on images; however, it can also be used to zoom in on a video.
