Which widget is generally not recommended for mobile app development?

The data grid is generally not recommended for mobile app development due to its inherent complexity and the way it presents information. Data grids are designed to display, manage, and manipulate large sets of data in a structured format, typically more suited for desktop applications where screen real estate is not a concern.

On mobile devices, screen size and user interaction are critical factors. A data grid can become crowded and cumbersome on smaller screens, leading to a poor user experience. Users may find it challenging to scroll through extensive data, and the readability of the information can be compromised.

In mobile development, it is often better to use simpler widgets that adapt well to smaller screens, allowing for easier scrolling and navigation. Widgets such as buttons, text areas, and images are more suitable because they can be easily scaled and optimized for touch interactions, providing an intuitive and user-friendly experience.
