StacMainAxisAlignment enum

Main-axis alignment options for flex layouts.

Defines how children are aligned along the main axis in flex layouts such as Row and Column widgets. The main axis is the primary direction of the flex layout:

  • In a Row, the main axis is horizontal (left to right)
  • In a Column, the main axis is vertical (top to bottom)

These values adapt to text direction for start and end alignments.

Values

start → const StacMainAxisAlignment

Align children to the start of the main axis.

In a Row: aligns to the start edge (left in LTR, right in RTL) In a Column: aligns to the top

end → const StacMainAxisAlignment

Align children to the end of the main axis.

In a Row: aligns to the end edge (right in LTR, left in RTL) In a Column: aligns to the bottom

center → const StacMainAxisAlignment

Center children along the main axis.

spaceBetween → const StacMainAxisAlignment

Place children with equal space between them.

The first child is placed at the start, the last child at the end, and remaining children are distributed with equal spacing between them. No space is added before the first or after the last child.

spaceAround → const StacMainAxisAlignment

Place children with equal space around them.

Each child gets equal space on both sides. This means the space between children is twice the space at the edges (start and end).

spaceEvenly → const StacMainAxisAlignment

Place children with equal space between and around them.

All gaps (including before the first and after the last child) have equal spacing, creating a uniform distribution.
