[Flutter] Flutter Exited (-30) using Neovim + DAP

I have been trying to use Flutter with nvim, but I keep on running into this issue.
I am using flutter-tools.nvim. I also use fvm ( thought this might be importnat ).
The issue is when enabling the debugger, the program crashes after the first file save with Exit Code (-30).

flutter doctor -v

I tried looking at others setups to find if something is out of the ordinary in mine, but didn't find anything that could be the cause.

Here is my flutter-tools.nvim config

return {
'akinsho/flutter-tools.nvim',
lazy = false,
dependencies = {
'nvim-lua/plenary.nvim',
'stevearc/dressing.nvim', -- optional for vim.ui.select
'mfussenegger/nvim-dap',
},
config = function()
local api = vim.api

-- Add the toggle log function
local function toggle_log()
local wins = api.nvim_list_wins()

for _, id in pairs(wins) do
local bufnr = api.nvim_win_get_buf(id)
if api.nvim_buf_get_name(bufnr):match '.*/([^/]+)$' == '__FLUTTER_DEV_LOG__' then
return vim.api.nvim_win_close(id, true)
end
end

pcall(function()
vim.api.nvim_command 'split + __FLUTTER_DEV_LOG__ | resize 15'
end)
end

-- Set up the keymap for toggling the Flutter dev log
vim.keymap.set("n", "<leader>fl", toggle_log, { desc = "Toggle Flutter dev log" })

I tried first without any nvim-dap config, and got this error.
After adding the dap config, I still get the same error.

Here is the dap config:

return {
{
"rcarriga/nvim-dap-ui",
dependencies = {
"mfussenegger/nvim-dap",
"nvim-neotest/nvim-nio"
}
},
{
"mfussenegger/nvim-dap",
dependencies = {
'nvim-neotest/nvim-nio',
'rcarriga/nvim-dap-ui',
},
event = 'VeryLazy',
config = function()
local dap = require('dap')

dap.configurations.dart = {
{
type = "dart",
request = "launch",
name = "Launch dart",
dartSdkPath = "$HOME/fvm/default/bin/flutter",
flutterSdkPath = "$HOME/fvm/default/bin/flutter",
program = "${workspaceFolder}/lib/main.dart", -- ensure this is correct
cwd = "${workspaceFolder}",
},
{
type = "flutter",
request = "launch",
name = "Launch flutter",
dartSdkPath = "$HOME/fvm/default/bin/flutter",
flutterSdkPath = "$HOME/fvm/default/bin/flutter",
program = "${workspaceFolder}/lib/main.dart", -- ensure this is correct
cwd = "${workspaceFolder}",
}
}
require("dapui").setup({
icons = { expanded = "▾", collapsed = "▸" },
layouts = {
{
elements = {
{ id = "scopes", size = 0.25 },
"breakpoints",
"stacks",
"watches",
},
size = 10, -- columns
position = "bottom",
},
},
})
end
}
}
