Configure useUnmergedTree flag

[Angakokv]

I need to find not merged element in compose tree. So how can I set useUnmergedTree to true to use in ViewBuilder?

I have a same question

Hey, I also got stuck with this problem. But after some digging I found two ways to specify useUnmergedTree option:

• Use KNode constructor with nodeMatcher parameter:

  val title = KNode(
  semanticsProvider = semanticsProvider,
  nodeMatcher = NodeMatcher(
      matcher = hasTestTag("title_test_tag"),
      useUnmergedTree = true,
  ),
  parentNode = this,
  )

• Overwrite useUnmergedTree variable in ViewBuilder block:

  val title: KNode = child {
  useUnmergedTree = true
  hasTestTag("title_test_tag")
  }

You can override constructors for KNode

class KAppNode : KNode {
    constructor(
        semanticsProvider: SemanticsNodeInteractionsProvider,
        nodeMatcher: NodeMatcher,
        parentNode: BaseNode<*>? = null,
    ) : super(
        semanticsProvider,
        nodeMatcher.copy(
            useUnmergedTree = true
        ),
        parentNode
    )

    constructor(
        semanticsProvider: SemanticsNodeInteractionsProvider,
        nodeMatcher: NodeMatcher,
    ) : super(
        semanticsProvider,
        nodeMatcher.copy(
            useUnmergedTree = true
        )
    )

    constructor(
        semanticsProvider: SemanticsNodeInteractionsProvider,
        viewBuilderAction: ViewBuilder.() -> Unit,
    ) : super(
        semanticsProvider,
        ViewBuilder().apply {
            useUnmergedTree = true
            viewBuilderAction()
        }.build()
    )
}

and use it like this

val title: KAppNode = child { hasTestTag("titleTestTag") }

Provided a global one KakaoCompose.Override.useUnmergedTree = true
