A really useful side effect of having composable previews built-in in Android Studio is that it forces you to build independent UI components. Similar to what widgetbook does, but integrated in IDE workflow. I'd argue that Flutter should deliver the same experience by default.

If this was Flutter, you could just copy the source code of the UINavigationBar and modify however you want.
Bad news for anyone hoping to recreate this UI in the new Mail app...
MobileCal is using a similar design and has done away the navigation bar's standard large title, replacing it with a custom _UINavigationBarPalette.
Too late for this release cycle, but if you'd like to see

Dart macros with JsonCodable experiment are super cool! On the left hand side is what you need to write, and then the compiler immediately creates the "augmentation" with basic json serialization logic.

Around 2003 in Chile, when the original trilogy of Star Wars began airing on television there, they did this funny thing to avoid cutting to commercial breaks. They stitched the commercials into the films themselves. Here is one of them, with the English dub added in.

It's super empowering that if you can interpolate (lerp) a class, you can use TweenAnimationBuilder for almost anything. Here you can see data entries and custom plot configuration being interpolated with nice curve on every state change. No animation controllers needed.

I think one of the greatest strengths of Flutter can be seen when working side by side with the product person.
Being able to prototype a real thing in minutes and then just save the file to let them try it on a physical device always feels amazing. Shortest feedback loop ever.
