Deep dive into Jetpack Compose layouts

Jetpack Compose offers a completely new layout model for building beautiful, performant UIs. We take a deep dive into the layout model, explaining how it works under the hood, the capabilities it has, how the bundled layouts and modifiers are built, and how you can easily create custom layouts and modifiers. This talk will help you understand Compose’s layout model so that you can use it to build exactly the layouts your app needs and write more performant code.

15:48 can you please clarify if the word "measure" on the slide at the timestamp provided is referring to the function MeasureScope.measure from interface LayoutModifier, the function measure from interface Measurable, or something else?

The part on the lambda-style animation progress value is really useful and non-obvious, thanks for that. And the rest of this great tutorial)

It would be interesting to know how the LazyColumn works, I tried to create a custom Layout and not call the place method for those measurables that I didn't want to be displayed on the screen, but using the layout inspector there were the outlines of the measurables not placed. But I suspect it was a problem related to the animation that I had given to my component and to an inaccuracy of the inspector. So if I don't call the place method for a measurable it is actually not placed on the screen? Is there a saving of resources?

A lot of engineering has gone into this framework

All looks and sounds great except 1 year later this is all going to end up being deprecated! 'now use this new amazing thing we just created'.

What a fascinating & informative video! Learned a lot and it does seem very simple now.

With navigation graph, you moved the fragment transaction logic from code to xml and told us that that is great. Now with compose, you are asking us to move the ui building from xml to code and telling us that this is great.
I think google has so much money and resources that their teams don't know what to do and the teams there are like creating their own shiny libraries without any harmony.

How to leave android development? fed up of this keep changing keep learning curve...

I'd rather to have an IDE to drag-and-drop UI components, then do some fine-tune by coding. Lambdas without auto-complete means we need to remember many things and hope them will remain undeprecated in the next few years...
