# Performance Skills

## What this domain covers

Finding and fixing jank, reducing rebuilds, using DevTools effectively, managing memory and images, and moving work off the UI thread.

## When to read it

- Scrolling stutters or frame times spike.
- Memory grows unexpectedly.
- Your app feels slow on low-end devices.

## Subtopics

- Rebuilds: [rebuilds.md](./rebuilds.md)
- DevTools: [devtools.md](./devtools.md)
- Memory: [memory.md](./memory.md)
- Images: [images.md](./images.md)
- Isolates: [isolates.md](./isolates.md)
- Jank: [jank.md](./jank.md)

## Decision guide

- If you need **why frames drop**, go to [jank.md](./jank.md) then [devtools.md](./devtools.md).
- If you need **to reduce rebuild cost**, go to [rebuilds.md](./rebuilds.md).
- If you need **to handle big images**, go to [images.md](./images.md).
