+.SYNOPSIS
+    Builds and packages a Flutter Windows application into a single executable.
+
+.DESCRIPTION
+    This script automates the entire process of creating a single-file executable for a Flutter Windows project.
+    It performs the following steps:
+    1. Checks for and installs Chocolatey if not present.
+    2. Installs Enigma Virtual Box and 7-Zip using Chocolatey.
+    3. Builds the Flutter application in release mode.
+    4. Packages the build output into a single EXE using Enigma Virtual Box.
+    5. If Enigma fails, it falls back to creating a 7-Zip self-extracting archive.
+    6. Places the final packaged executable in the 'dist' directory.
+
+.NOTES
+    - This script must be run with Administrator privileges to install software.
+    - An internet connection is required for the first run to download and install dependencies.
