Is there an existing issue for this?

Current Behavior

If flutter-tools is enabled there are duplicates in cmp suggestions.
Disabling flutter-tools makes it work correctly.

Here's my config:

lazy

{
	"akinsho/flutter-tools.nvim",
	lazy = false,
	dependencies = {
		"nvim-lua/plenary.nvim",
		"stevearc/dressing.nvim", -- optional for vim.ui.select
	},
	ft = "dart",
	config = true,
},

lsp.lua

local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities = require("cmp_nvim_lsp").default_capabilities(capabilities)
-- Setup language servers.
local lspconfig = require("lspconfig")
lspconfig.pyright.setup({})
-- lspconfig.dartls.setup({})

-- Global mappings.
-- See `:help vim.diagnostic.*` for documentation on any of the below functions
vim.keymap.set("n", "<leader>lD", vim.diagnostic.open_float)
vim.keymap.set("n", "[d", vim.diagnostic.goto_prev)
vim.keymap.set("n", "]d", vim.diagnostic.goto_next)
vim.keymap.set("n", "<leader>ld", vim.diagnostic.setloclist)

-- Use LspAttach autocommand to only map the following keys
-- after the language server attaches to the current buffer
vim.api.nvim_create_autocmd("LspAttach", {
	group = vim.api.nvim_create_augroup("UserLspConfig", {}),
	callback = function(ev)
		-- Enable completion triggered by <c-x><c-o>
		vim.bo[ev.buf].omnifunc = "v:lua.vim.lsp.omnifunc"

		local opts = { buffer = ev.buf }
		vim.keymap.set("n", "gD", vim.lsp.buf.declaration, opts)
		vim.keymap.set("n", "K", vim.lsp.buf.hover, opts)
		vim.keymap.set("n", "gi", vim.lsp.buf.implementation, opts)
		vim.keymap.set("n", "<C-k>", vim.lsp.buf.signature_help, opts)
		-- vim.keymap
		--     .set('n', '<Leader>sa', vim.lsp.buf.add_workspace_folder, opts)
		-- vim.keymap.set('n', '<Leader>sr', vim.lsp.buf.remove_workspace_folder,
		--                opts)
		-- vim.keymap.set('n', '<Leader>sl', function()
		--     print(vim.inspect(vim.lsp.buf.list_workspace_folders()))
		-- end, opts)
		-- vim.keymap.set('n', '<Leader>D', vim.lsp.buf.type_definition, opts)
		vim.keymap.set("n", "<Leader>lr", vim.lsp.buf.rename, opts)
		vim.keymap.set({ "n", "v" }, "<Leader>la", vim.lsp.buf.code_action, opts)
		-- vim.keymap.set('n', 'gr', vim.lsp.buf.references, opts)
		vim.keymap.set("n", "<Leader>lf", function()
			vim.lsp.buf.format({ async = true })
		end, opts)
	end,
})

cmp.lua

local cmp = require("cmp")
local luasnip = require("luasnip")

cmp.setup({
	snippet = {
		-- REQUIRED - you must specify a snippet engine
		expand = function(args)

	sources = cmp.config.sources({
		{ name = "luasnip" },
		{ name = "nvim_lsp" },
	}, { { name = "buffer" }, { name = "nvim_lsp_signature_help" } }),
})

-- Set configuration for specific filetype.
cmp.setup.filetype("gitcommit", {
	sources = cmp.config.sources({

	}, { { name = "buffer" } }),
})

-- Use buffer source for `/` and `?` (if you enabled `native_menu`, this won't work anymore).
cmp.setup.cmdline({ "/", "?" }, {
	mapping = cmp.mapping.preset.cmdline(),
	sources = { { name = "buffer" } },
})

-- Use cmdline & path source for ':' (if you enabled `native_menu`, this won't work anymore).
cmp.setup.cmdline(":", {
	mapping = cmp.mapping.preset.cmdline(),
	sources = cmp.config.sources({ { name = "path" } }, { { name = "cmdline" } }),
})

-- Set up lspconfig.
local capabilities = require("cmp_nvim_lsp").default_capabilities()
require("lspconfig")["tsserver"].setup({ capabilities = capabilities })
require("lspconfig")["dartls"].setup({ capabilities = capabilities })

Expected Behavior

Onlu unique options in cmp

Steps To Reproduce

.

Environment

- OS: MacOS 13.2.1
- Flutter version: 3.13.1
- Is flutter in $PATH: yes
- neovim version: v0.9.1

Anything else?

No response

My bad. I missed that there's require("lspconfig")["dartls"].setup({ capabilities = capabilities }) in cmp.lua.
Removed that and it works fine.
Sorry for redundant issue.
