[BUG] Null check operator used on a null value #511

Open minhnguyenandpad opened 2 years ago

minhnguyenandpad commented 2 years ago

Describe the bug I'm using the PhotoViewGallery.builder Here the code: PhotoViewGallery.builder( pageController: widget._pageController, itemCount: widget.urlImages.length, builder: (context, index) { final urlImage = widget.urlImages[index]; return PhotoViewGalleryPageOptions( imageProvider: NetworkImage(urlImage), minScale: PhotoViewComputedScale.contained, maxScale: PhotoViewComputedScale.contained * 4, ); }, onPageChanged: (index) => setState(() => this.index = index,), ),

To Reproduce When ever go in GalleryWidget, and slide the image => it show this error: Null check operator used on a null value => Then it show the image.

Expected behavior Stop showing this error
