To adhere to the Flutter style guide, consider linking to the definitions of the terms introduced. Using specific widget references like [AndroidView] and [UiKitView] provides better context for 'platform views'. Additionally, 'the Flutter engine' is the standard terminology used in the documentation.

/// This widget only filters content rendered by Flutter. It does not affect
/// platform views (such as [AndroidView] or [UiKitView]) because those views
/// are rendered by the platform itself, not by the Flutter engine.
