Analyzer quick-fix: Add import with show.

[lrhn]

The analyzer has a quick-fix, "Import library ...", for adding an import for a name that's not in the current library's scope.

I'd like a variant of that, which adds the same import, but with a show Name added, an Import library ... with show ..., or something like that.

The functionality to add a name to a show clause already exists:

• I can move the cursor the import and select "add explicit 'show' combinator" which adds the show clause for all already used names, and
• if I add the show Name myself, then writes the name of another declaration from the same library, I get an "Update library ... import" which adds the name to the show clause.

I just want to avoid moving the cursor away from where I'm writing, and get the show clause from the start.

Example of what I'd want:

void main() {
  Queue/* Press ctrl+. here, select "import library 'dart:collection' with show" */ queue;
  HashMap/* Press ctrl+.here, select "Update library 'dart:collection' import" */ map;
}
