What problem are you solving?
While one of the main selling points of Flutter is its rapid iterative development cycle that’s enabled by hot reload, it does require developers to have an active target device or simulator to work. In addition, it only allows for viewing the UI in a single configuration at a time without running an application on multiple devices, making it difficult for developers to visually verify the impact of variables like screen size, orientation, font size, and locale on their application.
Flutter Widget Previews is a development tool designed to improve the Flutter development workflow by allowing developers to quickly visualize and iterate on their widgets in various configurations without running the full application. This tool aims to significantly reduce development time and improve the overall developer experience by providing a fast and convenient way to experiment with widget variations, themes, and different device settings.
