Unable to debug flutter test

[n1h41]

When trying to debug test the following error is being thrown

neotest-dart: ...al/AppData/Local/nvim-data/lazy/neotest/lua/nio/init.lua:105: The coroutine failed with this message: ...AppData/Local/nvim-data/lazy/neotest/lua/nio/control.lua:208: ...ppData/Local/nvim-data/lazy/nvim-dap/lua/dap/session.lua:1420: Error running flutter: ENOENT: no such file or directory stack traceback: [C]: in function 'error' ...AppData/Local/nvim-data/lazy/neotest/lua/nio/control.lua:208: in function 'with' ...data/lazy/neotest/lua/neotest/client/strategies/init.lua:37: in function 'run' ...cal/nvim-data/lazy/neotest/lua/neotest/client/runner.lua:129: in function '_run_spec' ...cal/nvim-data/lazy/neotest/lua/neotest/client/runner.lua:89: in function <...cal/nvim-data/lazy/neotest/lua/neotest/client/runner.lua:88>

The test's are running without any issues when not debugging

This is my neotest config file

require("neotest").setup({ adapters = { require("neotest-dart")({ command = "flutter", use_lsp = true, }) } })

this is my dap configuration for flutter

`local dap = require('dap') local dapui = require('dapui')

dap.adapters.dart = { type = 'executable', command = vim.fn.stdpath('data') .. '/mason/bin/dart-debug-adapter.cmd', args = { 'flutter' }, options = { detached = false, }, }

dap.configurations.dart = { { type = "flutter", request = "launch", name = "Launch flutter", dartSdkPath = "C:/src/flutter/bin/cache/dart-sdk/", flutterSdkPath = "C:/src/flutter/", program = "${workspaceFolder}/lib/main.dart", cwd = "${workspaceFolder}", console = 'externalTerminal', }, { type = 'flutter', request = 'attach', name = 'Attach Program', dartSdkPath = "C:/src/flutter/bin/cache/dart-sdk/", flutterSdkPath = "C:/src/flutter/", program = "${workspaceFolder}/lib/main.dart", cwd = "${workspaceFolder}", console = 'externalTerminal', } }`

And this is my config file for flutter-tools.nvim

`local flutter = require('flutter-tools')

I see DAP can not find file Error running flutter: ENOENT: no such file or directory - please check if all files mentioned in your config exist, i.e. this one command = vim.fn.stdpath('data') .. '/mason/bin/dart-debug-adapter.cmd',

I hit the same problem because I was using puro which modifies the flutter path.

It seems neotest-dart accommodates raw flutter and fvm but not puro:

Here’s the line in nvim-dap where the error is thrown

Adding flutter to my env PATH fixed it, as a workaround.
