maybeNavigationModeOf static method

NavigationMode? maybeNavigationModeOf(
  1. BuildContext context
)

Returns MediaQueryData.navigationMode 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.navigationMode 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 NavigationMode? maybeNavigationModeOf(BuildContext context) => _maybeOf(context, _MediaQueryAspect.navigationMode)?.navigationMode;
