How to support longPress gesture on Gallery exmaple?

[SeakyLuo]

This is what I just found out according to the implementation of the PhotoViewGallery .

Don't use the PhotoViewGallery provided. Just use the PhotoViewGestureDetectorScope from the package to wrap your PageView.builder. If you want to zoom in and out the image, you can use the PhotoView from the package in the itemBuilder.
Then you wrap the whatever image widget with GestureDetector.

return PhotoViewGestureDetectorScope( axis: Axis.horizontal, child: PageView.builder( itemCount: totalPages, controller: _pageController, onPageChanged: _onPageChanged, itemBuilder: _buildPage, ), );
