Incular Docs

PositionedTransition animates a Positioned child's edges (all default None, like Positioned).

use incular::prelude::*;

fn main() {
    let app = Application::new(|_cx| {
        Stack::builder()
                .children(Vec::<Widget>::from([PositionedTransition::new(Text::new("Hi"))
                        .left(8.0)
                        .top(8.0)
                        .right(8.0)
                        .bottom(8.0).into()]))
                .build().into()
    })
    .expect("valid application");
    incular::run(app).expect("run application");
}

Setters: left, top, right, bottom (explicit impl setters); width and height exist as builder fields via TypedBuilder.
