## What it is
Keframe is a Flutter component library that optimizes UI fluency through frame-splitting rendering, reducing jank during page switches and fast scrolling of complex lists. It provides placeholder-based progressive rendering so heavy widgets build across multiple frames instead of blocking one.

## Use cases
- reduce jank when switching pages in flutter
- fix stuttering when scrolling long complex lists
- improve fps of flutter app on low-end devices
- progressively render heavy widgets with placeholders
- optimize list item build cost in flutter

## When to choose
- your Flutter app drops frames during page transitions or fast list scrolling
- you target low-end devices where heavy builds cause visible lag
- you want a drop-in widget-based optimization without rewriting your layout

## When to avoid
- your app is not built with Flutter
- your performance issues come from network or I/O rather than widget builds
- you need actively maintained support for the latest Flutter versions

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, animation
- domain: mobile-development, performance, frontend
- platform: cross-platform
- tags: flutter, frame-splitting, jank-optimization, smooth-scrolling, dart, mobile
