Flutter, Google’s toolkit for building cross-platform applications, hit version 1.0 today. Traditionally, the project focused on iOS and Android apps, but as the company announced today, it’s now looking at bringing Flutter to the web, too. That project, currently called Hummingbird, is essentially an experimental web-based implementation of the Flutter runtime.
“From the beginning, we designed Flutter to be a portable UI toolkit, not just a mobile UI toolkit,” Google’s group product manager for Flutter, Tim Sneath, told me. “And so we’ve been experimenting with how we can bring Flutter to different places.”
With tools like Electron, it’s easy enough to bring a web app to the desktop, too, so there’s now also a pathway for bringing Flutter apps to Windows and MacOS that way, though there is already another project in progress to embed Flutter into native desktop apps, too.
It’s worth noting that Google always touted the fact that Flutter compiled to native code — and the speed gains it got from that. Compiling to the web is a bit of a trade-off, though. Sneath acknowledged as much and stressed that Hummingbird is an experimental project and that Google isn’t releasing any code today. Right now, it’s a technical demonstration.
“If you can go native, you should go native,” he said. “Think of it as an extension of Flutter’s reach rather than a solution to the problem that Flutter itself is solving.”
In its current iteration, the Flutter web engine can handle most apps, but there’s still a lot of work to do to ensure that all widgets run correctly, for example. The team is also looking at building a plugin system and ways to embed Flutter into existing web apps — and existing web apps into Flutter web apps.
