maxLines property
An optional maximum number of lines for the text to span, wrapping if necessary. If the text exceeds the given number of lines, it will be truncated according to overflow and softWrap.
Implementation
int get maxLines => _textPainter.maxLines;
The value may be null. If it is not null, then it must be greater than zero.
Implementation
set maxLines(int value) {
assert(value == null || value > 0);
if (_textPainter.maxLines == value)
return;
_textPainter.maxLines = value;
_overflowShader = null;
markNeedsLayout();
}
