Struct ValueListenableBuilder 

pub struct ValueListenableBuilder;

Builds from a ValueNotifier’s value, and again whenever it changes — the reference’s ValueListenableBuilder.

use frus_widgets::{text, ValueListenableBuilder, ValueNotifier};

let count = ValueNotifier::new(0);
let label = ValueListenableBuilder::new(count.clone(), |_, n: &i32| Box::new(text(format!("{n}"))));
count.set(1); // the label shows 1 at the next frame
