Image.access within package does not work

[dmasotti]

Using Image.access with not null package results in an error (the app is working with no problem in both ios and android)

I couldn't reproduce this issue. Monarch loads images as expected using Image.asset with the package property set.

Widget monarch_purple() => Center(
        child: Column(children: [
      SizedBox(
        width: 350,
        child: Image.asset('assets/monarch_purple.png',
            package: 'scratch_image_core'),
      ),
    ]));

I created a repo so you can see the code I used. Could you use that repo to reproduce the issue you are experiencing? I gave you write access.

I 've done an example that explain the problem. This simple app loads an image in the emulator, but raise the error on monarch :

https://www.dropbox.com/s/eomdyxbp0zdcuv1/test_monarch.zip?dl=0

the problem appears when the image is an asset of a dependecy

[fertrig]

I got it to work using your code. I think the issue was the following:

• example is a flutter project
• test_monarch is a dependency of example
• test_monarch has story sample_app_stories.dart which is importing main.dart from the example project via import ../example/lib/main.dart';. This import creates a cyclical dependency.

Instead, I think you want the example project to have its own stories. If you do that, then the example stories can use example widgets without creating any cyclical dependencies. And then you can load asset images from the test_monarch project using Monarch.
