the logic in nvim-cmp, and how can i set up in blink.cmp

{
    "hrsh7th/nvim-cmp",
    optional = true,
    opts = function(_, opts)
      opts.sources = opts.sources or {}
      for i, source in ipairs(opts.sources) do
        if source.name == "nvim_lsp" then
          opts.sources[i] = {
            name = "nvim_lsp",
            ---@param entry cmp.Entry
            ---@param ctx cmp.Context
            entry_filter = function(entry, ctx)
              if ctx.filetype ~= "vue" then return true end

              local cursor_before_line = ctx.cursor_before_line
              -- For events
              if cursor_before_line:sub(-1) == "@" then
                return entry.completion_item.label:match "^@"
              -- For props also exclude events with `:on-` prefix
              elseif cursor_before_line:sub(-1) == ":" then
                return entry.completion_item.label:match "^:" and not entry.completion_item.label:match "^:on%-"
              -- For slot
              elseif cursor_before_line:sub(-1) == "#" then
                return entry.completion_item.kind == require("cmp.types").lsp.CompletionItemKind.Method
              else
                return true
              end
            end,

You can get filetype by vim.bo.filetype.

        providers = {
          lsp = {
            ---@type fun(ctx: blink.cmp.Context, items: blink.cmp.CompletionItem[])

              ---@diagnostic disable-next-line: redundant-return-value

                  col = c[2] + 1,
                  line = c[1] - 1,
                }
                local cursor_before_line = string.sub(cursor_line, 1, cursor.col - 1)
                -- remove text
                if item.kind == vim.lsp.protocol.CompletionItemKind.Text then return false end

                if vim.bo.filetype == "vue" then
