What's the use case for this? Or rather, what's the issue with the current beforeBundleCommand?

[amrbashir]

This is allows for some conditional logic based on which package type is being bundled.

Also maybe we should also add beforeEachTargetBuildCommand? but I don't see a use-case for it immediately, and probably will only affect when building for Android as it has more than one target being built in the same invoke of tauri android build?

I don't really think this PR is urgent or needed that much so I am fine to just keep it open until someone requests it or close it.

Ahh okay, my bad, i missed the TAURI_BUNDLER_PACKAGE_TYPE at the bottom (it's missing in the config description). Totally get it then 👍

[amrbashir]

good catch, I will add it to the docs

Closing until we see a use-case for this
