double
get
textScaleFactor
The number of font pixels for each logical pixel.
For example, if the text scale factor is 1.5, text will be 50% larger than the specified font size.
Implementation
double get textScaleFactor => _textPainter.textScaleFactor;
set
textScaleFactor
(double value)
Implementation
set textScaleFactor(double value) {
if (_textPainter.textScaleFactor == value) return;
_textPainter.textScaleFactor = value;
_overflowShader = null;
