AlignmentDirectional class
An offset that's expressed as a fraction of a Size, but whose horizontal component is dependent on the writing direction.
This can be used to indicate an offset from the left in TextDirection.ltr text and an offset from the right in TextDirection.rtl text without having to be aware of the current text direction.
See also:
- Alignment, a variant that is defined in physical terms (i.e. whose horizontal component does not depend on the text direction).
