textScaleFactor property

double 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.

• MediaQuery.textScaleFactorOf, a convenience method which returns the textScaleFactor defined for a BuildContext.

Implementation

double get textScaleFactor {
  if (_context == null) throw NoContextException();
  try {
    _mediaQuery = MediaQuery.maybeOf(_context!);
    if (_mediaQuery == null) throw NoContextException();
    return _mediaQuery!.textScaleFactor;
  } catch (e) {
    throw NoContextException();
  }
}
