Signing Options

before using the msix file, we sign it with certificate, this plugin use signtool to sign the file with default test certificate. you can use your own certificate, see the documentation on the configuration fields:

  • certificate_path
  • certificate_password
  • publisher
  • signtool_options

Also see how to create you own certificate (pfx) in SahajRana's Medium post

:label: Windows Store

If you publish your msix to Windows Store you dont need to sign it, Windows Store does it for you. To generate msix file for Windows Store use the --store flag or add store: true in msix configuration sction in your pubspec.yaml.


the configuration values publisher_display_name, identity_name, msix_version, publisher must be valid, you can find those values in your Windows Store Dashboard > Product > Product identity.

For more information, please see this tutorial: How to publish your MSIX package to the Microsoft Store

:gear: Command-Line Arguments

You can configuration values with command-line arguments instead of pubspec.yaml or combine them, see full list of arguments and example on this page
