[BUG] Wrap with widget code action does not enter select mode

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When using the 'Wrap with Widget' code action, a widget called "widget" is created. The cursor stays in the middle of the name and the placeholder is not selected.

Expected Behavior

It should enter select mode, allowing to select a widget. For example, when using the "Stateless widget" snippet, it creates a class called "MyWidget" and selects the name of the class. Entering text erases the placeholder.

It could also brind up a popup or query, for example as when renaming a variable.

Steps To Reproduce

I am using the following config (lazy.nvim):

  {
    "nvim-flutter/flutter-tools.nvim",
    dependencies = {
      "nvim-lua/plenary.nvim",
      "stevearc/dressing.nvim"
    },
    config = function ()
      local map = vim.keymap.set
      map("n", "fR", "<cmd> FlutterRun <cr>")
      map("n", "fd", "<cmd> FlutterDevices <cr>")
      map("n", "fr", "<cmd> FlutterRestart <cr>")
      map("n", "fo", "<cmd> FlutterOutlineToggle <cr>")
      require("flutter-tools").setup {
        flutter_lookup_cmd = "asdf where flutter",
        widget_guides = {
          enabled = true,
        }
      }
    end,
    ft = "dart"
  },

I have called the code action on the following snippet, at Placeholder

Widget test() {
  return Placeholder()
}

Environment

- OS:Fedora 40
- Flutter version: tested on
  - 3.19.5
  - 3.19.6
  - 3.22.0
  - 3.22.2
  - 3.24.3
  - 3.24.4

- Is flutter in $PATH: yes
- neovim version: 0.10.2

Anything else?

No response

Start by reproducing the Wrap with Widget code action on the provided Dart snippet at Placeholder, then trace the code-action entry point responsible for creating the widget name. The issue is done when the generated widget name is selected for replacement, matching the Stateless widget snippet behavior.
