maybeHeightOf static method

double? maybeHeightOf(
  1. BuildContext context
)

Returns height of 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 height of 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 double? maybeHeightOf(BuildContext context) =>
    _maybeOf(context, _MediaQueryAspect.height)?.size.height;
