Upcoming Flutter Feature: Platform-Specific Asset Inclusion (No More Manual Removal Needed)

[hm21]

Hey @espresso3389

First off, thank you for creating such an awesome package, it's truly a gem!

The reason I’m reaching out here is about manually removing assets, which we currently handle using dart run pdfrx:remove_wasm_modules. Honestly, that’s a clever solution, since it’s the only way to avoid bundling everything into the package. I’ve faced the same issue in my own Flutter packages, where all assets are included on every platform, even when they’re unnecessary.

That said, a few weeks ago I created that PR for Flutter that introduces the ability to define which platforms assets should be included on. That PR has just been merged. Since I’m not sure whether it’ll be highlighted in the next stable release, I wanted to mention it here so you’re already aware this feature is coming soon (I guess it won’t be included in 3.38 yet, but it should definitely arrive with 3.41).

The example code for that will look like that:

flutter:
  assets:
    # All Platforms
    - path: assets/logo.png
   
    # Only Web
    - path: assets/web_worker.js
      platforms: [web]

    # Only Desktop
    - path: assets/desktop_icon.png
      platforms: [windows, linux, macos]

Thanks, @hm21,
I always forget to run that commands, this will make things better

@hm21 Thank you for letting me know about the incoming feature.

I will update pdfrx to use the feature as soon as it is released on the stable channel.

This feature has been release with the current Flutter version 3.41. Please update if you can :)

We still need enable-dart-data-assets to enable the feature... I think we should wait for the feature being enabled on stable.
