BasicTextField bubble wrap

A little hack for adding (content) padding to your (decoration) boxes.

Centering in Compose

Let’s talk about centering things. There is no Modifier.center() in Compose, nor is there a Center composable, and I think the reason for that is because once you understand Compose's layout system you'll find those concepts redundant. In this article I'm going

Talk: Deriving derived state: derivedStateOf explained

This is a follow-up to my last snapshots talk, Opening the Shutter on Snapshots, and a companion to my article How derivedStateOf works: a deep d(er)ive. I've also written a bunch of articles on Compose state, check them out here. Slides: Deriving derived state: derivedStateOf explained

How derivedStateOf works: a deep d(er)ive

Compose's snapshot system is really neat, as I've talked and written about before. Once you know how it works, you can do some cool tricks with it, and derivedStateOf is a rich example of this. I recently gave a talk focused more on explaining the algorithms

Restartable functions from first principles

Often when thinking about Jetpack Compose state, we think in terms of what code will be re-executed when that state changes. We call functions that get re-executed like this “restartable functions”. Composable functions are generally restartable, but some other functions are restartable too, and you can make your own. 📖This

How I migrated my blog

About a week ago, I migrated my blog to a New blog site! As I explained in that post, I was previously posting on dev.to, and while it mostly worked fine to post the content, I did not like having my content live on a domain name and I

Talk: Reimagining text fields in Compose

I've spent the last six months working on a new BasicTextField. Check out what we've been working on!

Back on Code with the Italians to talk about BasicTextField2

I was very excited to get to chat more with Seb and Ivan, this time about something I’ve been working on at Google: the new BasicTextField!

I was on Code with the Italians!

Code with the Italians invited Halil and me on the show to talk about Compose Text. This was my first time here and we had so much fun! Seb and Ivan are excellent hosts.

Talk: Opening the shutter on snapshots

I had so much fun writing about Compose's state system that I decided to give a talk about how the snapshot system's algorithm works. I gave this talk initially at droidcon NYC in 2022, then again the next year at droidcon SF.
