Did you know you could submit your app's tests to the Flutter project, so that we would run them with every change to Flutter's APIs, and that we commit to not breaking you if you do this?

The problem with cross-platform frameworks, I'm told, is that they can never perfectly match the system widgets.

Every now and then I come across something that I wish I'd invented. This is one of them. Such a clean API, yet so powerful. We've long sought out how to make animations in Flutter easier, and this is far better than I had even hoped for.
As part of
#FlutterForward
I recorded a talk about the flutter_animate library I've been working on. It's a performant library that makes it simple to add almost any kind of animated effect to your UI.

This is your periodic reminder that if you develop a Flutter library you really should submit it to flutter/tests so that we can guarantee not to break your library and your library's users next time we update Flutter.

Thinking about that time I confused everyone by having the stack in the HTML parser spec grow down rather than up like a real stack, but nobody bats an eye at the way trees are always rooted at the top with leaves at the bottom, what is that, have you ever even seen a real tree.

Flutter's audio plugin tests need actual sound data to test playback, so we're brainstorming the best sounds to use, bearing in mind that if we forget to mute the devices in the lab, some poor tech is going to hear these every few hours. Rooster? Dripping water? Mewing kitten?

When writing error messages, even those that will "never" be seen or only ever be seen by bad actors, consider that one day that error message may be shown to one of your clients while they are in distress.

Sometimes a software project is faced with a trade-off, a decision where there are pros and cons for each option and none of the options are perfect.
Often, after years of living with a decision, the maintainers will switch to one of the other options.
Often, it's worse.

The basic idea is to create a set of low-level primitives based on Wasm, WebGPU, WebHID, and ARIA, so that frameworks in languages like Dart, Go, or Kotlin can build on a solid foundation rather than having to build apps by targeting a document format and JavaScript.

The pandemic has really changed my attitude on things that I used to consider inevitable. I used to get colds multiple times a year; I haven't had one since early 2020. Forget COVID for a minute, I just don't want to get another cold! They sucked! Sick days, better ventilation...
When pre-pandemic Americans had a cold, most carried on with their lives as usual. So long as they felt good enough, they’d go maskless to their jobs, gym, theater, bar, restaurant, etc without hesitation, making hundreds of others sick along the way. Why was that ever “normal”?
