Instructions

1. Configure Flutter SDK and Environment Variables Extract the Flutter SDK to a secure, user-writable directory (e.g., C:\develop\flutter). Do not place it in C:\Program Files\. Execute the following PowerShell command to append the Flutter bin directory to the user's PATH:

   $flutterBinPath = "C:\develop\flutter\bin"
   $currentUserPath = [Environment]::GetEnvironmentVariable("Path", [EnvironmentVariableTarget]::User)
   if ($currentUserPath -notmatch [regex]::Escape($flutterBinPath)) {
       [Environment]::SetEnvironmentVariable("Path", "$currentUserPath;$flutterBinPath", [EnvironmentVariableTarget]::User)
   }
   

2. Install Windows Tooling To compile Windows desktop applications, Visual Studio (not VS Code) is strictly required. Install Visual Studio with the "Desktop development with C++" workload. If automating via command line, use the following workload ID:
