maybeSizeOf static method

Size? maybeSizeOf(
  1. BuildContext context
)

Returns MediaQueryData.size from 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.size 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 Size? maybeSizeOf(BuildContext context) => _maybeOf(context, _MediaQueryAspect.size)?.size;
