Overview
Device Preview Plus allows developers to simulate how their Flutter app appears and behaves on different devices directly within the development environment. It provides accurate device-specific rendering, including screen size, orientation, and platform-specific UI behaviors. The package supports multiple platforms—Android, iOS, Web, macOS, Windows, and Linux—making it ideal for cross-platform testing. With real-time preview adjustments and customizable device profiles, it streamlines UI validation without requiring physical devices.
