Google announced at Google I/O 2026 that Canonical is the new lead maintainer and ‘strategic steward’ of Flutter desktop for Windows, macOS and Linux.
The news was shared in the ‘What’s new in Flutter’ presentation
“[The Flutter] desktop experience has reached a new level of maturity this year, driven by our incredible engineering partnership with Canonical, the publisher of Ubuntu”, says Kate Lovett, Engineer Manager on the Flutter Framework team at Google.
“This progress is fuelled by Canonical’s dedication to ensuring that Flutter delivers on every desktop” she adds.
Canonical made Flutter its ‘default choice’ for developing new Ubuntu apps in 2021. Since then the distro has created a variety of Flutter-based software for Ubuntu, including App Center, Firmware Updater and Security Center.
Going forward, Canonical will lead the Flutter desktop roadmap and oversee maintenance of Flutter’s desktop embedders. Google says the arrangement is the first step in a broader governance expansion, with more platform partners to follow.
Flutter desktop now supports tooltips and content-sized views, and can now create additional windows and dialogs so that developers can create “complex multi-window apps that feel native on Linux, Windows, and macOS”.
A leaner Flutter core
Canonical’s stewardship on the desktop wasn’t the only major change announced at the ‘What’s new in Flutter’ presentation at Google I/O 2026.
Google is moving the Material and Cupertino design libraries out of Flutter’s core SDK into standalone packages. Framework updates will no longer force developers to absorb breaking UI changes (like Liquid Glass) at the same time.
Foundational classes like Listenable are moving into pure Dart packages. This will let developers use them without having to pull in the entire Flutter framework as a dependency.
Flutter as a framework is being re-architected and slimmed down to allow it to move forward faster.
Given Flutter’s wide and diverse usage (including for in-car infotainment systems now), there’s plenty of enthusiasm for Flutter at Google. It isn’t jettisoning Flutter from its own orbit, even if Flutter team layoffs and rejigs did signpost a change in priorities.
But with Flutter moving towards a more collaborative governance model, this looks like Google doing a bit of maintenance offloading – handing stewardship of platforms it’s less invested in to parties who are – Canonical is taking that role on Flutter desktop.
