// This is also used to disambiguate how to render bidirectional text. For
// example, if the [text] is an English phrase followed by a Hebrew phrase,
// in a [TextDirection.ltr] context the English phrase will be on the left
// and the Hebrew phrase to its right, while in a [TextDirection.rtl]
// context, the English phrase will be on the right and the Hebrew phrase on
// its left.

// [Directionality], then this must not be null.
