textDirection property
The textDirection property controls the direction that children are rendered in. TextDirection.ltr is the default direction, so the first child is rendered to the left, with subsequent children following to the right. If you want to order children in the opposite direction (right to left), then use TextDirection.rtl.
This can be used with RTL (right to left) languages, but also when you want to align children to the right.
Implementation
final TextDirection textDirection;
