Enum CrossAxisAlignment 

pub enum CrossAxisAlignment {
    Start,
    End,
    Center,
    Stretch,
    Baseline,
}

How the children should be placed along the cross axis in a flex layout.

See also:

• RenderFlex, the flex render object.

Variants

Start

Place the children with their start edge aligned with the start side of the cross axis.

For example, in a column (a flex with a vertical axis) whose TextDirection is TextDirection::Ltr, this aligns the left edge of the children along the left edge of the column.

If this value is used in a horizontal direction, a TextDirection must be available to determine if the start is the left or the right.

If this value is used in a vertical direction, a VerticalDirection must be available to determine if the start is the top or the bottom.

End

Place the children as close to the end of the cross axis as possible.

For example, in a column (a flex with a vertical axis) whose TextDirection is TextDirection::Ltr, this aligns the right edge of the children along the right edge of the column.

If this value is used in a horizontal direction, a TextDirection must be available to determine if the end is the left or the right.

If this value is used in a vertical direction, a VerticalDirection must be available to determine if the end is the top or the bottom.

Center

Place the children so that their centers align with the middle of the cross axis.

This is the default cross-axis alignment.

Stretch

Require the children to fill the cross axis.

This causes the constraints passed to the children to be tight in the cross axis.

Baseline

Place the children along the cross axis such that their baselines match.

Consider using this value for any horizontal main axis (as with a row) where the children primarily contain text.

Because baselines are always horizontal, this alignment is intended for horizontal main axes. If the main axis is vertical, then this value is treated like Start.

Children who report no baseline will be top-aligned. No RenderBox reports a baseline yet, so every child is top-aligned; see PORTING.md.
