Dart how to hide cmd when using Process.run?

After building the Dart application, function Process.run starts to open a visible cmd for a second-two.

final bool checkEnvironment = environment == ShellEnvironment.powershell;
ProcessResult result = await Process.run(
  checkEnvironment ? 'powershell' : command,
  checkEnvironment ? [command] : args,
  runInShell: checkEnvironment,
);

Link with example(gif): https://i.sstatic.net/orSzG.jpg For each command it opens a new cmd window.

If i launch the application with idea(not a build version) - such thing does not happen

Also tried this version - still the same problem:

final bool checkEnvironment = environment == ShellEnvironment.powershell;
ProcessResult result = await Process.run(
  'start',
   checkEnvironment ? ['/min', 'powershell', '-command', command] : ['/min', 'cmd', '/c', command],
   runInShell: true,
);

Found an article that runInShell creates a new window so i removed it, but the result is still the same.

final bool checkEnvironment = environment == ShellEnvironment.powershell;
ProcessResult result = await Process.run(
  checkEnvironment ? 'powershell.exe' : 'cmd',
  checkEnvironment ? ['-command', command] : ['/c', command],
);

You might have found a solution here: https://github.com/flutter/flutter/issues/47891. BUT do not use it! It does not work with window 7 and creates a problem when after closing the app user cannot delete the app due to one instance of CMD is still running.

Try this approach instead

// Attach to console when present (e.g., 'flutter run') or create a
// new console when running with a debugger.
if (!::AttachConsole(ATTACH_PARENT_PROCESS) && ::IsDebuggerPresent()) {
  CreateAndAttachConsole();
} else {
  AllocConsole();
  ShowWindow(GetConsoleWindow(), SW_HIDE);
}

You can replace it in windows/runner/main.cpp
