Jetpack Compose: State

Learn how state flows through your app in Jetpack Compose and how the framework can automatically update to display new values. Join engineer Florina Muntenescu to see how to create automatically observable state, how to retain state across recompositions or configuration changes and how to structure your composables for optimal data flow.

this video in 5 minutes explains more than other videos in an hour

I swear that it is the most useful 5 minutes explanation I've ever find in whole Android Developers video or text documentation

As someone who was often skeptical about changes introduced in the Android ecosystem, I have to say I tried Compose and so far I think it's a huge improvement.

A simple rule of thumb I like to use: If multiple components use the same state the component in the highest architectural layer should hold the state and the other components should just observe it. Learned this from a book from 1999 (Refactoring) and now as android views became stateless I can apply it in Android. Today is a good day :)

Probably the most useful 5 minutes video out there, explaining the most important core concepts of Jetpack Compose. Well done and thanks.

Going back to Android Development after Flutter will now be easy! This is beautiful! Thank you!

Had some issues remembering a state when using LazyColumn in Compose for Desktop. Once you used rememberSaveable a lightbulb went off and made the change in my code. Worked like a charm. Thanks!

Incredible tutorial. Short and to the point but I love how it shows each possible implementation and then builds on it. Very excited to start integrating compose into our app!

[louiscad]

Thank you for that great overview of usage of state in Compose!
The design of the API is great!

[pxnx]

simple and well understandable. Thanks Florina🐣

[vikas.patidar]

This is simple and great overview. I would like to suggest about including a short intro about the specific dependencies used as well.

[mianala]

This is what I was looking for. Thanks.

[cubevlmu]

[ugur]

It says "Unresolved reference: viewModel".
During default parameter assignment in - fun HelloScreen(helloViewModel : HelloViewModel = viewModel()) - function.
What could be the reason, what am i missing, can anyone help ?

[gsmtechzambia]

I'm new to compose, and see people saying managing state in hard. From first Impressions, the video seems to show something similar to what we do with our eyes closed to ReactJS

[BearkFearGamer]

For me, its a react in Kotlin and i love it!

[dmorales]

Wonderfull Explain!!! More Videos like this please!!!!

Compose should have a way (maybe a DSL) to deal with common cases like a text field showing typed text, with less boilerplate.

Because if we need to write presentation logic to each component work properly on screen, maintain large or very complex UI can be really challenging!

Maybe we could pass the mutable state as only parameter on the Outline text field, and when we do that, the DSL already know that value is also bound with it.
