High resolution image zoom result in black screen

[liushiqi9]

I am running the demo with one of my high resolution image. And I can see the image, even zoom it a little bit, but after I zoom it to certain ratio, it will black out, and when it zoom back, it will show the picture again. I think this is a bug.

Image:

Code:
`import 'package:flutter/material.dart';
import 'package:pinch_zoom_image/pinch_zoom_image.dart';
import 'package:cached_network_image/cached_network_image.dart';
import 'package:photo_view/photo_view.dart';

class PinchZoomImageDemo extends StatelessWidget {
@OverRide
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Pinch Zoom Image Demo'),
),
body: ListView(
children: [
PinchZoomImage(
image: CachedNetworkImage(
imageUrl: web_url_of_my_image',
),
zoomedBackgroundColor: Color.fromRGBO(240, 240, 240, 1.0),
),
],
),
);
}
}`
