✒️ Signing Options

.msix installer must be sign with certificate (.pfx)

• This package will automatically sign your app with build in test certificate.
• If you publish your app to the Windows Store, the app will automatically sign by the store.
• If you need to use your own certificate, use the configuration fields:certificate_path, certificate_password

Note: by default, this package will install the certificate on your machine, you can disable it by using the --dontInstallCert flag or the configuration: dont_install_cert: true

Windows Store

To generate msix file for publish to the Windows Store, use the --store flag or add store: true in msix configuration section in your pubspec.yaml.

Note:

For Windows Store publication 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 about publish to the Windows Store see: How to publish your MSIX package to the Microsoft Store

📁 .dll Files And Assets (FFI Library)

To include your .dll and other third party assets in your msix installer, you can use the configuration field: assets_directory_path:

assets_directory_path:  'C:\Users\me\flutter_project_name\myAssets'

1. create new folder in your root project folder (where pubspec.yaml is located)
2. put there all your assets (.dll etc.)
3. in your application code, use the FFI package like so:

var helloLib = ffi.DynamicLibrary.open('myAssets/hello.dll');
var helloLib2 = ffi.DynamicLibrary.open('myAssets/subFolder/hello2.dll');

Note: don't use absolute path:

var absolutePath = path.join(Directory.current.path, 'myAssets/hello.dll');
var helloLib = ffi.DynamicLibrary.open(absolutePath);
