Overview
Dynamic Widget is a backend-driven UI toolkit that enables developers to build dynamic user interfaces using JSON. The JSON structure closely mirrors Flutter widget code, making it intuitive for Flutter developers to design and render UIs programmatically from server responses. It supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, allowing consistent UI rendering across environments. This package simplifies the creation of flexible, data-driven interfaces without requiring app updates for UI changes.
Use cases
- Server-driven UI updates
- Rapid prototyping with JSON
