Struct Positioned 

pub struct Positioned {
    pub id: Option<NodeId>,
    pub left: Option<f32>,
    pub top: Option<f32>,
    pub right: Option<f32>,
    pub bottom: Option<f32>,
    pub width: Option<f32>,
    pub height: Option<f32>,
    pub child: Option<Box<Node>>,
}

Absolutely positions a child within a ZStack.

Specify one or more edge offsets (left, top, right, bottom) and optional explicit width/height. Omitting both horizontal offsets (or both vertical offsets) leaves the child unconstrained on that axis.

Example

// Pin a badge to the top-right corner
Positioned {
    top: Some(8.0),
    right: Some(8.0),
    child: Some(Box::new(badge_widget)),
    ..Default::default()
}

Fields

id: Option<NodeId>

Explicit node identity.

left: Option<f32>

Distance from the left edge of the parent.

top: Option<f32>

Distance from the top edge of the parent.

right: Option<f32>

Distance from the right edge of the parent.

bottom: Option<f32>

Distance from the bottom edge of the parent.

width: Option<f32>

Explicit width override.

height: Option<f32>

Explicit height override.

child: Option<Box<Node>>

The child widget to position.
