unaryPlus

operator fun <T> FieldVisualizer<T>.unaryPlus(): Form.Field<T>(source)

DSL for adding a Field with an initial value of Invalid to a Form. The FieldVisualizer can put the created field into a Valid state; so there is no guarantee that the created field is actually invalid.

Form {
    this(
        + field { ... }, // Field defaults to invalid unless its visualizer sets a valid value
        ...
    ) { first, ... ->
        ...
    }
}
