Passing Decoration box as children widget , breaking widget

[vikaspw]

I have defined BasicTextField Widget
schema
@widget(9)
data class BasicTextField (
@Property(1) val value: String,
@Property(2) val onValueChange: ((String) -> Unit)? = null,
@children(1) val decorationBox: (() -> Unit) = {}
)
Compose UI implementation -
BasicTextField (
modifier = androidModifier.focusRequester(FocusRequester()),
value = textFieldValue.copy(
text = state.text,
selection = TextRange(state.selectionStart, state.selectionEnd),
),
onValueChange = { newValue :TextFieldValue ->
textFieldValue = newValue
stateChanged(newValue)
},

    decorationBox = { decorationBox.widgets[0].value() }
)

when i pass decorationBox as Children , it wont take input while writing same code in Compose UI works.
param- decorationBox: @composable (innerTextField: @composable () -> Unit) -> Unit
am i doing some wrong thing here?

I'm not sure what type your decorationBox is, but if it's a ComposeWidgetChildren then you should be calling decorationBox.Render() inside that lambda which will automatically place the children and update them as they change.
