integratedTerminal Not Starting, unconfigured externalTerminal Shows Warning, but launching integratedTerminal correct

[IgnatevKirill3341]

I'm trying to set up a debugger for Dart using nvim-dap. I’ve encountered an issue with the console configuration and would appreciate guidance.

Problem:
When I configure console = "integratedTerminal", terminal doesn’t open (opening DAP Console) and all program output appears in DAP REPL. However, switching to an unconfigured console = "externalTerminal" works, but I get a warning: "requested external terminal, but none configured. Fallback to integratedTerminal".

Relevant Configuration Snippet:

dap.adapters.dart = {
   type = "executable",
   command = "dart",
   args = {"debug_adapter"}
 }
 dap.configurations.dart = {
   {
     type = "dart",
     request = "launch",
     name = "Launch Dart Program",
     program = "${file}",
     cwd = "${workspaceFolder}",
     args = {},
     console = "integratedTerminal"
   }
 }
