textScaleFactor property
Deprecated. Will be removed in a future version of Flutter. Use textScaler instead.
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.
Defaults to the MediaQueryData.textScaleFactor obtained from the ambient MediaQuery, or 1.0 if there is no MediaQuery in scope.
Implementation
final double? textScaleFactor;
