I like this idea, though what you currently have doesn't compile because the quick_actions_platform_interface doesn't have that parameter. Check out https://github.com/flutter/flutter/blob/master/docs/ecosystem/contributing/README.md#changing-platform-interface-method-parameters

 lib/main.dart:56:9: Error: No named parameter with the name 'localizedSubtitle'.
         localizedSubtitle: 'Action one subtitle',
         ^^^^^^^^^^^^^^^^^
 ../../../../../.pub-cache/hosted/pub.dev/quick_actions_platform_interface-1.0.6/lib/types/shortcut_item.dart:11:9: Context: Found this candidate, but the arguments don't match.
   const ShortcutItem({

Also quick_actions_ios will need its CHANGELOG updated. Take a look at that wiki page for more details about how to contribute to packages.
Thank you!

Ok sorry @jmagman, I've added the deps override (as indicated in the documentation), the quick_actions_ios CHANGELOG and also the quick_actions_platform_interface CHANGELOG.

Now I wait for the review, than I'll make a new PR to update only the platform interface

Are you able to reproduce this test timeout locally?

Please see the CHANGELOG style guide linked from the PR checklist.

[stuartmorgan]

Please revert all of the quick_actions_android override entries since the package won't need any changes.

[stuartmorgan]

Please see the versioning policy linked in from the PR checklist.

[stuartmorgan]

As above, please see the versioning policy.

[stuartmorgan]

Platform interface packages should not make claims about what implementation packages, which are a higher level, do or don't do. This should just say that it's ignored by platforms that don't support it.

[stuartmorgan]

It's not clear to me that this is a common enough option that we actually need to update the README and example app to demonstrate it.

[stuartmorgan]

This should just be inlined below, as it doesn't seem like the local variables are adding any value here. (The ones above may well be left over from a direct Pigeon conversion, as they would have been more useful prior to Pigeon.)

[stuartmorgan]

This change should have corresponding native testing.
