Cannot Visualize Colors

[AminBhst]

I have flutter-tools setup but the color visualizer does not work. It only shows the color white no matter what the selected color is.
Here is my config below :

 require("flutter-tools").setup {
    debugger = {
      enabled = true,
      run_via_dap = true,
    },
    outline = { auto_open = false },
    decorations = {
      statusline = { device = true, app_version = true },
    },
    widget_guides = { enabled = true, debug = true },
    dev_log = { enabled = false, open_cmd = "tabedit" },
    lsp = {
      color = {
        enabled = true,
        background = true,
        virtual_text = true,
        virtual_text_str = "■",
      },
      settings = {
        showTodos = true,
        renameFilesWithClasses = "prompt",
      },
      on_attach = require("ryewell.lsp.handlers").on_attach,
      capabilities = require("ryewell.lsp.handlers").capabilities,
    },
  }

I am facing the same issue

It works for me:

My setup:

    color = { 
      enabled = true,
      background = false, 
      foreground = false, 
      virtual_text = true, 
      virtual_text_str = "■", 
    },

It works in both 3.3.10 and 3.7.0 Flutter versions.
What flutter versions you are using? What Neovim version?

[Chaitanyabsprip]

nvim version : NVIM v0.9.0-dev-763+ge86d2734a
flutter version: 3.3.10

        color = {
          enabled = true,
          background = false,
          foreground = false,
          virtual_text = true,
          virtual_text_str = '■',
        },

Maybe transparent background is used?
I see it is not supported yet:

There is a config.background_color property that could be set then.

oh alright, what is the format of the configuration property? I tried rrggbb with and without the # char and it is not working

[Chaitanyabsprip]

I followed the code to understand it, made it work.

        color = {
          enabled = true,
          background = false,
          background_color = { r = 19, g = 17, b = 24},
          foreground = false,
          virtual_text = true,
          virtual_text_str = '■',
        },

The color I mentioned is basically the stock bg color of the color scheme I am using

Great! I created PR to update README with this missing background color config.
