Overview
json_view is a Flutter package designed to efficiently display JSON data with high performance. It uses lazy loading to render JSON tree nodes on demand, minimizing jank and improving responsiveness—especially when handling large datasets. Inspired by Chrome DevTools, it supports intuitive navigation and visual inspection of complex JSON structures across multiple platforms. The package is ideal for debugging, development tools, or any app requiring interactive JSON visualization.
