This is possible now because the latest ubuntu-app-platform snap build incorporates the standard Qt 5 libraries, the QML (Qt Meta Language) runtime, the Ubuntu UI (User Interface) toolkit, and their dependencies. The Oxide web engine library based on Chromium and related QML bindings is also bundled in the ubuntu-app-platform snap, so the new Snaps should now be significantly smaller. At the moment of writing this article, the Snapcraft Snap creator utility does not support the changes made to the ubuntu-app-platform snap, so it will still crawl for dependencies when attempting to package your apps as Snaps. An updated Snapcraft version will soon be made available for supported Ubuntu platforms. Also, if your app depends on a specific Qt module, you’ll need to add it to the build.
