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
• DevTools: devtools.md
• Memory: memory.md
• Images: images.md
• Isolates: isolates.md
• Jank: jank.md

Decision guide

• If you need why frames drop, go to jank.md then devtools.md.
• If you need to reduce rebuild cost, go to rebuilds.md.
• If you need to handle big images, go to images.md.
