What it does
Restart App iOS Engine Restart is an agent skill from gabrimatic/restart_app. Configure or debug restartapp Flutter engine restart on iOS, including AppDelegate and UIScene registration, custom native shells, engine factories, and explicit notification fallback.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/host-setup.md`).
It sits in Mobile, covering Cross-platform mobile apps. It works with iOS, Flutter and Dart. The repository describes itself as: A Flutter plugin to restart or relaunch Flutter apps with platform-specific behavior, including opt-in iOS Flutter engine restart. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit e9f6582. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Restart App iOS Engine Restart loads about 1.1k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 54 tokens; SKILL.md has 506 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

iOS Flutter engine restart
AppDelegate setup
Inspect the app's existing AppDelegate.swift, scene lifecycle, and engine
ownership before editing them. Preserve existing plugin and lifecycle wiring.
Read the AppDelegate examples for the matching lifecycle:
- UIScene with
FlutterImplicitEngineDelegate: retain registration of the initial engine indidInitializeImplicitFlutterEngineand configure registration of replacement engines separately. - Classic
FlutterAppDelegate: retain normal initial registration inapplication(_:didFinishLaunchingWithOptions:)and add the replacement engine callback. - Custom engine or add-to-app: use
setEngineFactoryonly when the host owns engine creation, startup, and plugin registration. The package example uses the standard UIScene setup; custom hosts must preserve their own ownership.
RestartAppPlugin.configureEngineRestart is a Swift API, not a Dart method.
Rebuild the iOS app after editing AppDelegate; hot reload does not apply native changes. Xcode 27 requires UIScene
lifecycle adoption. Updating only the restart callback does not migrate the host.
Restart behavior
Restart.restartApp()uses the configured engine path on iOS. ExplicitRestartMode.flutterEngineselects the same path. Missing configuration returnsIOS_ENGINE_RESTART_NOT_CONFIGURED; it never falls back implicitly.RestartMode.processfails withIOS_PROCESS_RESTART_UNSUPPORTED.forceKillhas no iOS effect. Do not propose private APIs or an exit/relaunch trick to implement automatic process restart.- Engine restart creates a new engine, runs Dart, registers plugins, replaces the Flutter view controller, and destroys the old engine context. The iOS process, native globals/singletons, unrelated engines, and native resources retained by plugins can survive. Do not promise code-push compatibility or native-state reset without testing that integration.
- Save any unsaved changes the app needs to keep before restarting. Request
restart on the main isolate while the app is active.
A successful
RestartResultacknowledges scheduling; factory or swap failures after that response are logged natively and cannot change the returned result.

Failure handling
| Result code | Action |
|---|---|
IOS_ENGINE_RESTART_NOT_CONFIGURED | Configure AppDelegate, rebuild, and check capability again. |
IOS_APP_NOT_ACTIVE | Wait for foreground activation and an intentional restart action. |
IOS_NO_ACTIVE_WINDOW | Check scene/window lifecycle or supply the correct windowProvider. |
IOS_UNSAFE_ROOT_REPLACEMENT | Supply a host-specific viewControllerInstaller; do not overwrite a native shell with a generic Flutter root. |
IOS_RESTART_ALREADY_IN_PROGRESS | Prevent duplicate restart requests. |
IOS_PROCESS_RESTART_UNSUPPORTED | Use configured engine restart if it meets the requested behavior. |
For a custom shell, select the intended scene explicitly. The default installer
expects a FlutterViewController at the window root. beforeRestart runs before
replacement engine creation; afterRestart runs after installation and before
the old engine is destroyed. Keep app-specific cleanup consistent with that order.
Notification fallback
RestartMode.notificationFallback requests notification permission, schedules a
local notification, and closes the app. The user must tap the notification to
reopen it. Select this mode only when that interaction is intended. notificationFallback capability does not mean permission
is granted. Handle NOTIFICATION_DENIED, AUTHORIZATION_ERROR, and
NOTIFICATION_FAILED as failed results. Custom title/body alone do not select
this mode. The plugin uses local notifications and needs no push entitlement.
Verification
Check capability after the host is configured, then test default and explicit engine restart in the foreground. Confirm a fresh Dart boot, saved data, working plugin calls/platform views, and a second successful restart. Inspect native logs if success is returned but the old UI remains. Verify native state assumptions and code-push behavior in a real release build.
