Allow users and/or packages to create custom versions of "Wrap with ..." actions

[DanTup]

It doesn't seem like there's an issue specifically for this, but there has been some discussion across various other issues (and PRs like Dart-Code/Dart-Code#4232).

There is a desire to have more options in the "Wrap with..." actions list. Sometimes package-specific widgets, and sometimes widgets that users feel they use a lot. Including all of them in the default list could make it unwieldy (and doesn't handle packages). Perhaps analysis server plugins are the best way to handle this, but they might also be a bit complex for simple uses where a user just wants a simple extra wrap for a widget.

It's not great, but I noticed that user-defined snippets in VS Code can use $TM_SELECTED_TEXT to wrap a selection. So VS Code users can create their own snippets to do this, but they will need invoking/selecting from the command palette (maybe there's a way to optimise this, but I couldn't see anything obvious).

(ofc, for something this simple you should just use wrap with widget... but if you have something more complex, you can add multiple parameters, tabstops etc. in snippets)

I saw this comment here from the PR mentioned above.

I was thinking if this ever becomes a thing, there could be a way for the user to set which assists they'd like to see. Like a list option in vs code configs or something where they tick whatever they want to show. WDYT?

Not really sure how could we make that reflect the options on the analyzer, but maybe not to select what you want but possibly the other way around. Like what you'd like to hide kind of a thing.

I was thinking if this ever becomes a thing, there could be a way for the user to set which assists they'd like to see.

Do you mean allowing the user to also hide some of the existing values (like "Wrap with Padding"), or also hide other kinds of assists (like "Change to double quotes")?

Assuming the former and that the goal is to reduce the number of entries, something that might not be obvious (and doesn't negate the desire for this, but might help in the meantime), is that you can type to jump around the code actions list. For example here, I hit Ctrl+. and then typed column and it jumped to that action in the list:

I meant only hiding the "Wrap with ..." assists. Great help, will use your tip!

However, your comment got me wondering if the user's created "Wrap with" could be added to non-Widget classes for dart packages that add wrappers to their own or Dart base classes. Or even for List and other base classes like ValueNotifier if these assists can be made by users.

I think that would be more difficult, because the current assists are specifically written for Widgets with build, and child/children. For non-widget classes, presumably these patterns might not be the same. However, for your own classes, analysis server plugins might be a way to achieve some of this (although at this point they're still a work in progress).
