msix 2.8.14

A command-line tool that create Msix installer from your flutter windows-build files.

MSIX is a Windows app packaging format from Microsoft that combines the best features of MSI, .appx, App-V, and ClickOnce to provide a modern and reliable packaging experience.

This package offers a command line tool for creating MSIX installers from your Flutter app, making it easy to publish your app to the Microsoft Store or host it on a website.

📋 Installation

In your pubspec.yaml, add the msix package as a new dev dependency with the following command:

PS c:\src\flutter_project\> flutter pub add --dev msix

📦 Creating an MSIX installer

To create a MSIX installer from your package, run the following two commands:

PS c:\src\flutter_project\> flutter build windows
PS c:\src\flutter_project\> flutter pub run msix:create

The flutter build windows command compiles release executables and dependencies into the build\ subdirectory. In turn, the msix:create command bundles those files along with other necessary dependencies into an MSIX install file.

Configuring your installer

You will almost certainly want to customize various settings in the MSIX installer, such as the application title, the default icon, and which Windows capabilities your application needs. You can customize the generated MSIX installer by adding declarations to an msix_config: node in your pubspec.yaml file:

msix_config:
  display_name: MyAppName
  publisher_display_name: MyName
  identity_name: MyCompany.MySuite.MyApp
  msix_version: 1.0.0.0
  logo_path: C:\<PathToIcon>\<Logo.png>
  capabilities: "internetClient,location,microphone,webcam"

✒️ Signing options

Published MSIX installers should be signed with a certificate, to help ensure that app installs and updates come from trustworthy sources.

• For development purposes, this package is configured by default to automatically sign your app with a test certificate, which makes it easy to test your install prior to release.
• If you publish your app to the Microsoft Store, the installation package will be signed automatically by the store.
• If you need to use your own signing certificate, for example to release the app outside of the Microsoft Store, you can use the configuration fields certificate_path and certificate_password to configure a certificate of your choice.

You can also provide custom options to the signing tool with the --signtool-options command, as shown above. For more information on available options, see the signtool documentation. Note that using this option overrides the certificate_path and certificate_password fields.

Note: By default, the MSIX package will install the certificate on your machine. You can disable this by using the --dontInstallCert flag, or the YAML option dont_install_cert: true.

Publishing to the Microsoft Store

To generate an MSIX file for publishing to the Microsoft Store, use the --store flag, or alternatively add store: true to the YAML configuration.

Note: For apps published to the Microsoft Store, the configuration values publisher_display_name, identity_name, msix_version and publisher must all be configured and should match the registered publisher and app name from the Microsoft Store dashboard, as per this screenshot.
