showing ellipses when expanded

[ghost]

HI, I don't know if this is only with me, but I see the '...' ellipses when the text is expanded.

Same thing here.

I'm using trimExpandedText: '' even though the "show less" phrase disappears

Maybe this issue is by this code, please check it
TextSpan _delimiter = TextSpan(
text: _readMore
? widget.trimCollapsedText.isNotEmpty
? widget.delimiter
: ''
: widget.trimExpandedText.isNotEmpty
? widget.delimiter
: '',
style: _defaultDelimiterStyle,
recognizer: TapGestureRecognizer()..onTap = _onTapLink,
);
