maybeTextScalerOf static method
- BuildContext context
Returns the MediaQueryData.textScaler for the nearest MediaQuery ancestor or null if no such ancestor exists.
Use of this method will cause the given context
to rebuild any time that
the MediaQueryData.textScaler property of the ancestor MediaQuery
changes.
Prefer using this function over getting the attribute directly from the
MediaQueryData returned from maybeOf, because using this function will
only rebuild the context
when this specific attribute changes, not when
any attribute changes.
Implementation
static TextScaler? maybeTextScalerOf(BuildContext context) => _maybeOf(context, _MediaQueryAspect.textScaler)?.textScaler;
