Error building dmg file

[nzkn]

I have an issue when trying to build dmg:

Package is installed globally: dart pub global activate flutter_distributor as well as locally in pubspec.yaml: flutter_distributor: 0.0.6

There is distribute_options.yaml in the root of project: https://gist.github.com/nzkn/7aeb5090d035b9424537265b1f90997c

And there is also make config in macos/packaging/dmg/make_config.yaml: https://gist.github.com/nzkn/392e5eefc9346123d5fe68609bc9594f

The build is triggered with the following command, which I run from the project root: flutter_distributor release --name sand --jobs macos-dmg

I am getting following issue when trying to build .dmg file:

After the command execution fails I can see the following content of the dist folder:

Am I doing anything wrong?

Also another important note:

1. I have appdmg installed globally
2. When I run the same appdmg dist/1.4.7/velocityOS-1.4.7+1.4.7-macos_dmg/make_config.json dist/1.4.7/velocityOS-1.4.7+1.4.7-macos.dmg command manually from the project root .dmg is created successfully. It seems like this issue only occurs when the command is executed by dart

Please do not depend on flutter_distributor in your project, it needs to be installed globally. Please provide the information of flutter doctor

I tried to remove project flutter_distributor dependency and run without it, still the same result

[Edit]: Let me know if you need any extra information from me, please

This should be caused by the absence of the appdmg command, please install it according to the documentation.

npm install -g appdmg
