How do I enable the new `experimental multithreaded recomposition`(yes, I am aware of the problems)?
Leland said on the stream that it is now possible and you can turn it on and play.
I'm reading the source for the CompositionContext class, but I don't know how to use it. Can anyone please help?
Thanks 🙂

On Composition or Recomposer there's a method called runConcurrent....something I think.

nothing there similar 😞

I definitely know Adam Powell worked on this, but I don't want to mention him for trifles. 😬

Recomposer.runRecomposeConcurrentlyAndApplyChanges is what it's called lol.

How should I use it?

I thought it would be something like a compiler flag

No idea. Maybe source code of setContent might have a hint.

1. make a Recomposer (probably with AndroidUiDispatcher.Main as its effect context)
2. get it running by calling the method described above, use AndroidUiDispatcher.Main for that call (edit: launch the call into AndroidUiDispatcher.Main and pass some background dispatcher like Dispatchers.Default or a background single-threaded dispatcher as the recompose context parameter)
3. create a ComposeView and set its parentCompositionContext to the Recomposer you created
4. Attach your ComposeView to a window

you'll probably run into some bugs right away 🙂
