This is not working, because no gn target I can find is listing $root_out_dir/dart-sdk as an output.
The zip target template requires its inputs to be the output of some target that it depends on directly or indirectly.

No target in Dart's sdk build rules lists the directory as an output, only the individual files that are created. So a major addition to the build rules would be needed to make a target whose output was the entire directory.

I would suggest removing the approval of this PR until it can be fixed.

Closing the PR. Either more extensive changes need to be made, or the archive creation must be moved out of the build process.

I was able to fix this PR by switching from the zip_bundle template to the zip_bundle_from_file template.
Because that template has no inputs, the target correctly depends on its create_sdk dependency, and
rebuilds the zip file if that target is rebuilt. If the create_sdk dependency does not need to be rebuilt, then
the zip file is left as-is.

Thanks for the info Casey! I can add entitlement config for this block.

Do you want to add it in this PR, or should I land it?

Feel free to land it sir. Its just a for my info thing that I will remember to do
