Unable to open large size (500MB) image in flutter image widget-CodePudding

The

The same image when I open in any other windows built in image viewer then it opens up. In flutter if with same code Image.file('smallSize.jpg') it works fine.

@override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( // Here we take the value from the MyHomePage object that was created by // the App.build method, and use it to set our appbar title. title: Text('Image Viewer'), ), body: Center( child: //not working Image.file(File('images/largeImage.JPG')),//515MB //working Image.file(File('images/smallImage.JPG')), //10MB ), ); }

I also tried with extended_image library but it doesn't display anything (just a blank window) and no exceptions.

Widget build(BuildContext context) { return Scaffold( appBar: AppBar( // Here we take the value from the MyHomePage object that was created by // the App.build method, and use it to set our appbar title. title: Text('Image Viewer'), ), body: Center( child: ExtendedImage.file( width: 600, height: 400, File('images/Panel.JPG'), //cancelToken: cancellationToken, ), ), ); }

Below is the flutter.doctor summary:

could you please test below code, to be honest I am not sure about this.

Image.file(File(path), width: 200, height: 200, cacheHeight: 200, cacheWidth: 200, )
