screenPixelRatio property
double
screenPixelRatio
screenPixelRatio
is a MediaQuery
function.
The number of device pixels for each logical pixel. This number might not
be a power of two. Indeed, it might not even be an integer. For example,
the Nexus 6 has a device pixel ratio of 3.5.
Implementation
double get screenPixelRatio {
if (_context == null) throw NoContextException();
try {
_mediaQuery = MediaQuery.maybeOf(_context!);
if (_mediaQuery == null) throw NoContextException();
return _mediaQuery!.devicePixelRatio;
} catch (e) {
throw NoContextException();
}
}
