Canonical takes over Flutter desktop maintenance & roadmap

Canonical 接管 Flutter 桌面端的维护与路线图规划

Google confirmed at Google I/O 2026 that Canonical is the new lead maintainer and ‘strategic steward’ of Flutter desktop for Windows, macOS and Linux. The announcement of an expanded partnership with Canonical came during the ‘What’s new in Flutter’ presentation at Google I/O 2026, where Kate Lovett, Engineer Manager on the Flutter Framework team at Google, touched on their existing work: “[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”. She later confirmed that Canonical’s ‘deep technical expertise’ will now oversee maintenance of Flutter for desktop and take charge of its roadmap. The arrangement is said to be the first step in a wider governance expansion for Flutter.

Google 在 Google I/O 2026 大会上确认，Canonical 已成为 Flutter 桌面端（支持 Windows、macOS 和 Linux）的首席维护者和“战略管家”。这一扩大合作伙伴关系的公告是在 Google I/O 2026 的“Flutter 新特性”演讲中发布的。Google Flutter 框架团队的工程经理 Kate Lovett 在会上谈到了双方现有的合作成果：“得益于我们与 Ubuntu 发行商 Canonical 之间出色的工程合作，[Flutter] 桌面体验在今年达到了一个新的成熟度。”她随后确认，Canonical 将凭借其“深厚的技术专长”负责 Flutter 桌面端的维护工作，并主导其路线图规划。据悉，此举是 Flutter 更广泛治理架构扩张的第一步。

Canonical made Flutter its ‘default choice’ for developing new Ubuntu desktop apps in 2021. Since then the distro has created and shipped a range of Flutter-based software for Ubuntu, including App Center, Firmware Updater and Security Center.

Canonical 在 2021 年将 Flutter 选定为开发新款 Ubuntu 桌面应用的首选方案。自那时起，该发行版已开发并发布了一系列基于 Flutter 的软件，包括 App Center（应用中心）、Firmware Updater（固件更新程序）和 Security Center（安全中心）。

A leaner Flutter core

更精简的 Flutter 核心

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. On desktop, Flutter 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”.

Canonical 接管桌面端并非 Google I/O 2026“Flutter 新特性”演讲中宣布的唯一重大变革。在桌面端，Flutter 现已支持工具提示（tooltips）和内容自适应视图，并能创建额外的窗口和对话框，使开发者能够构建在 Linux、Windows 和 macOS 上拥有原生体验的“复杂多窗口应用”。

Google also moved 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 or newer Material Design) at the same time. Foundational classes like Listenable transition out into pure Dart packages so that the wider Dart community can use them without needing to pull in the entire Flutter framework as a dependency.

Google 还将 Material 和 Cupertino 设计库从 Flutter 核心 SDK 中剥离，转为独立的软件包。这意味着框架更新将不再强制开发者同步接受破坏性的 UI 变更（如 Liquid Glass 或更新的 Material Design）。像 Listenable 这样的基础类也被迁移至纯 Dart 软件包中，以便更广泛的 Dart 社区能够使用它们，而无需将整个 Flutter 框架作为依赖项引入。

The presentation also covered a raft of AI-focused features and tooling updates, though most are aimed at mobile and full-stack Dart developers. 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 by handing stewardship of platforms it’s less invested in to parties who are – in this case, Canonical.

此次演讲还涵盖了一系列以 AI 为重点的功能和工具更新，尽管其中大部分针对的是移动端和全栈 Dart 开发者。鉴于 Flutter 应用场景广泛且多样（目前甚至包括车载信息娱乐系统），Google 内部对 Flutter 依然充满热情。尽管 Flutter 团队的裁员和重组确实预示着优先级发生了变化，但 Google 并未将其抛弃。随着 Flutter 向更具协作性的治理模式转型，这看起来更像是 Google 在进行“维护减负”——将那些投入较少的平台管辖权移交给更有意愿的合作方，而 Canonical 正是这一策略的执行者。
