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

[payolin]

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?

I investigated a bit and found, that if

capabilities.experimental = { snippetTextEdit = true }

is provided, then Wrap with widget... returns the result in LSP snippet format. Here is the action output:

  kind = "refactor.flutter.wrap.generic",                                                                                                                                
  title = "Wrap with widget..."                                                                                                                                          
}     

That is how, I think, VSCode handles it. But I haven't found any easy way how to expand this snippet from code action. Neovim has some basic support for expanding snippets via vim.snippet.expand(), but not sure if it is possible to expand it here. I think at some point this should be supported directly by neovim, maybe via vim.lsp.util.apply_workspace_edit().

Hi. great plugin by the way!

I have the same problem, I guess there is no current solution?
