//! This example shows off how buttons are able to use any widget, including
//! buttons, as their "label". The widget hierarchy constructed for this example
//! is:
//!
//! ```text
//! ┏ Align
//! ┃ ┏ Stack
//! ┃ ┃ ┏ Button
//! ┃ ┃ ┃ ┏ Stack
//! ┃ ┃ ┃ ┃ ┏ "Yo dawg!"
//! ┃ ┃ ┃ ┃ ┣ Button
//! ┃ ┃ ┃ ┃ ┃ ┏ Stack
//! ┃ ┃ ┃ ┃ ┃ ┃ ┏ "I heard you like buttons"
//! ┃ ┃ ┃ ┃ ┃ ┃ ┣ Button
//! ┃ ┃ ┃ ┃ ┃ ┃ ┃ ╺ "So I put buttons in your buttons"
//! ┃ ┃ ┣ clicked_button Label
//! ```
