textDirection property Null safety

TextDirection textDirection

The directionality of the text.

This decides how the TextAlign.start, TextAlign.end, and TextAlign.justify values of textAlign are interpreted.

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.

This must not be null.

Implementation

TextDirection get textDirection => _textPainter.textDirection!;
void textDirection= (TextDirection value)

Implementation

set textDirection(TextDirection value) {
  assert(value != null);
  if (_textPainter.textDirection == value)
    return;
  _textPainter.textDirection = value;
  markNeedsLayout();
}
