  • If the result of the condition or is true, the text component Text becomes true;
  • If it is false, it attributes the text the value false;
fun screen() = Screen(
    navigationBar = NavigationBar(
        title = "Operations",
        showBackButton = true
    ),
    child = Container(
        children = listOf(
            Text(text = "The text bellow will show if 4 is below 5 or not"),
            Text(expressionOf(
                    "@{condition(lt(4, 5), 'less then 5', 'greater then 5')}")
            ).setStyle{ backgroundColor = "#00FF00" }
        )
