if I change a value of some prop inside

@Model

object, will it trigger rerender of a whole "tree"? I mean not only the composable that uses this object, right?

@Model

observes only variables, not constants. If a property is constant, what’s the point in observing it? It will never change

there is a special observable list implementation -

modelListOf<Foo>()

but the case of using mutableList with val, the value inside of the list could change

@Muh Rahmatullah if the

Foo

is also a

Model

it should work

@Luca Nicoletti I tried that too but it’s not working as well

no, it will not work with just mutableList and Model annotated Foo, as there is no changes within Foo, it is a new item added into the list

tried the modelListOf and the recompose process now works, thanks @Andrey Kulikov @Luca Nicoletti

@Andrey Kulikov That’s what I said:

Only if

Foo

changes

yes, the composable using specific Model annotated class instance will be automatically recomposed(this will trigger all the required remeasuring/redrawing). if you use it inside measuring lambda - it will be remeasured. if you use inside drawing lambda - redrawn

🙂 Thanks

Note thate you don’t need

ModelList

if you just use an immutable list pattern, and instead of using

MutableList

with

add

, you could use

List

with

plus

(list concatenation)
