So I’m just wondering, but how does ambient work? It seems to be kinda similar to react’s context but I’m not sure if I’m right. How would I make my own ambient things, and would it be appropriate to use it for things like network?

[Adam Powell]

yes, you've understood its nature correctly. Context is a bit of an occupied namespace on Android already. 🙂

[Adam Powell]

Make your own with Ambient.of

[Adam Powell]

They're quite easy to make a mess of implicit dependencies with and should be used sparingly

[andrew]

And when you make an ambient, the ambient state acts global, and can be used everywhere?

[andrew]

Or is there a concept of providers like with react

[Adam Powell]

there are providers. myAmbient.Provider(value) { ComposableStuff() } is the usage

[Adam Powell]

and you can consume them with an effect: +ambient(myAmbient)

[Adam Powell]

the scope of an ambient read will recompose if the provider value changes and we can skip recomposing things in between

[andrew]

Okay, I’ll try them out and try and get the grasp of them then
