[BUG] AssertionError_throwNew when first launch the PhotoView;

[inloop-tech]

Describe the bug I have created a screen with only photo_view widget. When first open that screen, my visual studio code will stop and pointed the error_patch.dart line 46 native "AssertionError_throwNew"; When I click the button to continue to execute the code. The next times open the screen seems it can normally display. However, open and close the same screen serval time, it shows a memory leak in my vs code debug code.

To Reproduce

1. Create a screen with CarouselSlider.
2. Click the CarouselSlider to open a screen to display photo using photo_view widget
3. Start debug to execute the code
4. Click on the CarouselSlider
5. Stop and and pointed the error_patch.dart line 46 native "AssertionError_throwNew";
6. Continue execute the code
7. Open and close the screen with photo_view widget
8. Sometime throw a memory leak error

class _ProductImgViewerState extends State { int _current = 0; List imageSliders;

Widget build(BuildContext context) { return Scaffold( appBar: T2AppbarBack("Index"), body: Container( constraints: BoxConstraints.expand( height: MediaQuery.of(context).size.height, ), child: PhotoView( imageProvider: NetworkImage('https://picsum.photos/250?image=9'), )), ); } }

Nice, in order to have enough information to work on this, would you follow the issue template?

A trace for the error would help as well.

This is also happening for me, there is no error being thrown even when the code is wrapped inside a try catch block

Here's my env

[✓] Flutter (Channel stable, 1.22.6, on macOS 11.2.3 20D91 darwin-x64, locale en-PH)

photo_view '0.10.3'

Here's my code

Scaffold(
  appBar: AppBar(),
  body: PhotoView(
    imageProvider: NetworkImage('any image url here'),
  ),
);

I'm also having this same issue. Maybe it's related to this: https://github.com/fireslime/photo_view/issues/341

This PR is closed, but I'm having the exact same issue. Doesn't matter what image provider I use. If I replace PhotoViewer() with any other widget it's works as intended
