    This is one of my two screens, when first launched , as statusApp.lang has just been initialized the getListHeadlines is called, if I change the statusApp.fontSize, the headlines are redrawn but the headlines are not loaded which is what I want, but If I go to the next screen which is a detail screen, when I came back by pressing the back button and assigning the application screen to be again the headlines screen, I've got the elements reloaded as if stattusApp.lang would have changed.

    Looks like you're mutating the list held by the
    state
    but not the
    state
    itself. The code above is roughly equivalent to
    var list = mutableListOf(...)
    but compose only knows when you change the
    var
    , not its contents.
    Try
    remember { modelListOf(...) }
    Or use read-only or immutable lists as the value of the
    State
    Rather than having both the list reference and the list itself both mutable
    modelListOf
    will give you a mutable list where compose is tracking its content changes

    Well, I'm sure I'm doing it wrong, but is almost fascinating how far you can go wrong, I've got exactly what I want except that oddity on the backpress. I've found the information on state and effects to be rather scarce , and it looks some times that you have more than one option to obtain the same thing and that's confusing ... But I want to highlight that with all it's oddities I'm very satisfied with the results, I have just one file 500 lines and the equivalent in regular android would have been vastly more cumbersome.
