I have created a Flutter app to be deployed to Windows desktop. It will be deployed to the Microsoft store via a MSIX package. The Flutter app utilizes a third party application. The installer for the third party application is a MSI file. I would like the third party app installer to run when my Flutter app is installed.
I have previously done something similar with Electron by using a .nsh script to execute the third party installer. The .nsh script was part of a NSIS installer package. The script executed with "msiexec /i "$PLUGINSDIR\third-party-installer.msi" /qn"
