Function Canvas 

pub fn Canvas(
    __arg0: Modifier,
    on_draw: impl Fn(&mut dyn DrawScope) + 'static,
) -> usize

Draws custom content through a DrawScope. The modifier sets canvas bounds. The draw scope also measures and draws text with the app’s fonts.

Example

use cranpose_ui::*;

#[composable]
fn ColorPanel() {
    Canvas(Modifier::empty().size_points(200.0, 100.0), |scope| {
        scope.draw_rect(Brush::solid(Color::RED));
    });
}

For text, use DrawTextStyle, DrawScope::measure_text and DrawScope::draw_text_from to place a label within the canvas.
