Photo_view: PhotoViewGallery with non PhotoView widget child

[rostopira]

Is your feature request related to a problem? Please describe.
I'm building some kind of app internal gallery, and it has videos
I've tried to just include PhotoView widget in PageController, but with this approach PhotoView doesn't work at all

Describe the solution you'd like
I want PhotoViewGallery.builder to be able to accept non PhotoView widget

Best api, IMHO, would be like following:

    PhotoViewGallery.builder(
      pageController: PageController(initialPage: initialIndex),
      itemCount: assets.length,
      builder: (_, i) =>
        PhotoViewGalleryPageOptions(
          imageProvider: assets[i].isVideo ? null : assets[i].image,
          notImage: assets[i].isVideo ? assets[i].videoWidget : null,
        ),
    ),

I've found PhotoView.customChild but I want video widget appear as is, taking whole available space and no scaling

Perhaps a new constructor such as PhotoViewGalleryPageOptions.customChild would help you.

Yeah, I will try to implement it
UPD: well, no luck, feel like an idiot now :D

@rostopira added custom child support on #131

      PhotoViewGalleryPageOptions.customChild(
            child: Container(
              width: 300,
              height: 300,
              child: SvgPicture.asset(
                item.resource,
                height: 200.0,
              ),
            ),
            childSize: const Size(300, 300),
            initialScale: PhotoViewComputedScale.contained,
            minScale: PhotoViewComputedScale.contained * (0.5 + index / 10),
            maxScale: PhotoViewComputedScale.covered * 1.1,
            heroTag: item.id,
      )
