# Send Flutter to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Quick Reference

TopicFilesetState, state loss, keysstate.mdbuild method, context, GlobalKeywidgets.mdFutureBuilder, dispose, mountedasync.mdContext after pop, deep linkingnavigation.mdconst, rebuilds, performanceperformance.mdPlatform channels, null safetyplatform.md

### Critical Rules

setState after dispose — check mounted before calling, crashes otherwise
Key missing on list items — reordering breaks state, always use keys
FutureBuilder rebuilds on parent rebuild — triggers future again, cache the Future
BuildContext after async gap — context may be invalid, check mounted first
const constructor — prevents rebuilds, use for static widgets
StatefulWidget recreated — key change or parent rebuild creates new state
GlobalKey expensive — don't use just to access state, pass callbacks instead
dispose incomplete — cancel timers, subscriptions, controllers
Navigator.pop with result — returns Future, don't ignore errors
ScrollController not disposed — memory leak
Image caching — use cached_network_image, default doesn't persist
PlatformException not caught — platform channel calls can throw
