Omi Mobile App — Flows & Exploration

This skill teaches you the Omi Flutter mobile app's navigation structure, screen architecture, and widget patterns. Use it when developing features (to understand how the app works), fixing bugs (to navigate to the affected screen), or verifying changes (to confirm your code works in the live app).

How to Explore the App

You can interact with the running app via agent-flutter — a CLI that taps widgets, reads the widget tree, and captures screenshots through Flutter's Marionette debug protocol.

Setup

# 1. Emulator must be running
adb devices                          # should show emulator-5554
# If not: sg kvm -c "$ANDROID_HOME/emulator/emulator -avd omi-dev -no-window -gpu swiftshader_indirect -no-audio -no-boot-anim &"

# 2. Set system language to English (REQUIRED — non-English IME breaks text input)
adb shell "settings put system system_locales en-US"
adb shell "setprop persist.sys.locale en-US"

# 3. App must be running in debug mode with flutter run stdout captured
cd app && flutter run -d emulator-5554 --flavor dev > /tmp/omi-flutter.log 2>&1 &
# Wait for "VM Service" line to appear in the log

# 4. Connect agent-flutter (AGENT_FLUTTER_LOG must point to flutter run stdout, NOT logcat)
AGENT_FLUTTER_LOG=/tmp/omi-flutter.log agent-flutter connect
agent-flutter snapshot -i --json    # see what's on screen

Prerequisites:

• AVD name: omi-dev (check: $ANDROID_HOME/emulator/emulator -list-avds)
• KVM access required: user must be in kvm group (sg kvm -c "..." if not in current session)
• App package: com.friend.ios.dev (dev flavor)
• System language must be English — non-English IME breaks fill commands
• App must be authenticated and connected to the correct backend (local, dev, or prod — depends on the task)
• Marionette already integrated: marionette_flutter: ^0.3.0 in pubspec.yaml

Commands

Command	Purpose	Example
snapshot -i --json	See all interactive widgets with refs, types, bounds	agent-flutter snapshot -i --json
press @ref	Tap a widget by ref	agent-flutter press @e3
press x y	Tap by coordinates (ADB input tap)	agent-flutter press 540 1200
press @ref --adb	Tap by ref using ADB (for stale refs)	agent-flutter press @e3 --adb
dismiss	Dismiss system dialogs (location, permissions)	agent-flutter dismiss
find type X press	Find widget by type and tap	agent-flutter find type button press
find text "X" press	Find by visible text and tap	agent-flutter find text "Settings" press
find type X --index N press	Tap Nth match (0-indexed)	agent-flutter find type switch --index 0 press
fill @ref "text"	Type into text field	agent-flutter fill @e7 "search"
scroll down/up	Scroll current view	agent-flutter scroll down
back	Android back button	agent-flutter back
screenshot PATH	Capture current screen	agent-flutter screenshot /tmp/screen.png

Key rules:

• Refs go stale frequently (Flutter rebuilds widget tree aggressively) — always re-snapshot before every interaction, not just after mutations.
• find type X is more stable than hardcoded @ref numbers.
• AGENT_FLUTTER_LOG must point to flutter run stdout (not logcat).
• After hot restart: disconnect → wait 3s → connect.
• Widget text labels are often null — use type, flutterType, or bounds to identify.

Recovery

# "No isolate with Marionette" → bring app to foreground + reconnect
adb -s emulator-5554 shell am start -n com.friend.ios.dev/com.friend.ios.MainActivity
agent-flutter disconnect && agent-flutter connect

# Unhealthy widget tree → hot restart
kill -SIGUSR2 $(pgrep -f "flutter_tools.*run" | head -1)
sleep 3 && agent-flutter disconnect && agent-flutter connect

Widget Patterns

Bottom navigation bar:

• 4 InkWell widgets at bounds.y > 780, sorted left-to-right by bounds.x
• Detect with: snapshot -i --json → filter flutterType == 'InkWell' and bounds.y > 780
• Navigate home: press the leftmost one

Settings gear:

• Rightmost button widget in the top bar
• Detect with: sort buttons by bounds.x descending, take first

Settings rows:

• gesture widgets with bounds.width > 300
• Position-based: Profile is y=150-200, Developer Settings is y=400-520 after scrolling

Switch toggles:

• Type switch in snapshots
• Press to toggle ON/OFF (no separate ON/OFF actions)

Bottom sheet pickers:

• Open when you press a settings row
• Language items appear as gesture rows with bounds.y > 380
• Many items — use scroll if needed

Changing Locale

DEVICE=emulator-5554; APP_PKG=com.friend.ios.dev

# Read current
adb -s $DEVICE shell "run-as $APP_PKG cat shared_prefs/FlutterSharedPreferences.xml" | grep app_locale

# Change to Spanish, hot restart to apply
adb -s $DEVICE shell "run-as $APP_PKG cat shared_prefs/FlutterSharedPreferences.xml" > /tmp/prefs.xml
sed -i 's|flutter.app_locale">[^<]*|flutter.app_locale">es|' /tmp/prefs.xml
adb -s $DEVICE push /tmp/prefs.xml /data/local/tmp/FlutterSharedPreferences.xml
adb -s $DEVICE shell "run-as $APP_PKG cp /data/local/tmp/FlutterSharedPreferences.xml shared_prefs/FlutterSharedPreferences.xml"
kill -SIGUSR2 $(pgrep -f "flutter_tools.*run" | head -1)
sleep 3 && agent-flutter disconnect && agent-flutter connect

Prerequisites Reference

Every flow lists prerequisites: — conditions that MUST be true before running. These describe the real user state — no bypasses, no shortcuts. Test the app the way users experience it.

Prerequisite	What it means	How to achieve (Android)	How to achieve (iOS)
auth_ready	User completed sign-in (Google or Apple), app shows home screen	Run bash setup.sh android → launch app → complete Google Sign-In flow → complete onboarding	Run bash setup.sh ios → launch on simulator or device → complete Google/Apple Sign-In → complete onboarding
signed_out	Fresh app, user NOT signed in, shows Get Started screen	Uninstall + reinstall, or clear app data via Settings → Apps → Omi → Clear Data	Delete app from simulator/device and reinstall
microphone_permission	App has mic permission granted	When app requests mic permission during use, tap "Allow". Or pre-grant: adb shell pm grant com.friend.ios.dev android.permission.RECORD_AUDIO	When app requests mic permission, tap "Allow" in the iOS permission dialog
ble_on	Bluetooth enabled on device	Enable Bluetooth in device Settings → Connected Devices. Emulators/simulators do not support BLE — requires physical device	Enable Bluetooth in device Settings. iOS Simulator has no BLE — requires physical iPhone
omi_device_connected	Omi hardware paired and connected via BLE	Power on Omi device within BLE range → app auto-discovers on home screen → tap Connect. Physical device only	Same — power on Omi, app discovers it. Physical iPhone only
phone_number_verified	Phone number added and verified in settings	Settings → Phone Calls → add phone number → receive SMS → enter code. Requires real phone number	Same flow — requires real phone number that receives SMS
developer_settings_enabled	Developer Settings screen is open	Settings drawer → scroll down → tap "Developer Settings" (visible to all users)	Same navigation path
adb_access	Shell access for locale/prefs manipulation (Android only)	Debug build + adb in PATH. Verify: adb shell run-as com.friend.ios.dev ls shared_prefs/	Not applicable — iOS equivalent uses xcrun simctl for simulator or Xcode for device

Prerequisite dependency chain

signed_out ─── (fresh install, no prior state)

auth_ready ─── launch app → sign in with Google/Apple → complete onboarding
  │             (this is the REAL user flow — no bypasses)
  ├── microphone_permission  (grant when prompted, or pre-grant via platform tools)
  ├── developer_settings_enabled  (navigate in-app to Settings → Developer Settings)
  ├── phone_number_verified  (in-app SMS verification — manual step)
  ├── ble_on + omi_device_connected  (physical device + physical Omi hardware)
  └── adb_access  (Android debug builds only — for locale manipulation)

Platform setup

# Android: setup + build + launch
cd app && bash setup.sh android
# → completes: keystore, Firebase config, .dev.env, flutter run --flavor dev
# → sign in with Google when app launches, complete onboarding

# iOS: setup + build + launch
cd app && bash setup.sh ios
# → completes: Firebase config, .dev.env, flutter run --flavor dev
# → sign in with Google/Apple when app launches, complete onboarding

Important: Both platforms require completing the real sign-in and onboarding flows. Never bypass auth or onboarding — these are user-facing flows that must work correctly.

YAML Flow Schema (v2)

Each flow file uses schema v2:

version: 2
name: string          # Flow identifier
description: string   # What this flow covers
app: com.friend.ios.dev
evidence:
  video: true
covers: [string]      # Source files this flow exercises
preconditions: [string]  # Conditions required — see Prerequisites Reference above
steps: [Step]         # Ordered list of actions

Each step has these fields:

Field	Required	Description
id	yes	Step ID (S1, S2, ...)
name	yes	Short description
do	yes	Instructions for executing
verify	no	true = must be verified even during snapshot replay
expect	no	Assertions (text_visible, interactive_count)
evidence	no	Screenshot filename (.webp preferred)
note	no	Edge case notes

Supported expect kinds:

Kind	Fields	Example
text_visible	values: [string]	Verify specific text appears
interactive_count	min: number	Verify minimum interactive widgets

Navigation Graph (flow-walker verified)

Real navigation edges verified by flow-walker run11 on Pixel 7a (26 screens, 44 edges, depth 3). Screen names mapped from fingerprint IDs to semantic names.

Verified Flows (v2 flow-walker)

Only flows that have been executed, verified, and pushed through the v2 flow-walker pipeline are listed here. Each has a .snapshot.json for fast replay.

Flow	Steps	Prerequisites	What it tests	Reports
flows/login.yaml	5	signed_out	Auth screen → Google Sign-In → consent → OAuth → home	normal, replay
flows/onboarding.yaml	9	signed_out + auth	Name → Language → Found Omi → Permissions → Review → Speech → Knowledge → Complete → Home	normal, replay
flows/logout.yaml	5	auth_ready	Home → Settings → Sign Out → Confirm → Auth screen	normal, replay
flows/ask-omi-chat.yaml	9	auth_ready	Home → Ask Omi → Chat page → Type message → AI response → Chat apps drawer → Home	normal

When you modify a Dart file, check if any flow's covers: includes it. If so, that flow describes the user journey your change affects — use it to understand context and verify your work.

Verification & Evidence

After making changes, verify them in the live app:

1. Navigate to the affected screen using the commands above
2. Check that your changes appear (snapshot, screenshot)
3. Test interactions (press buttons, fill fields, scroll)
4. Capture evidence: agent-flutter screenshot /tmp/evidence.png
5. Generate video: ffmpeg -framerate 1 -pattern_type glob -i '/tmp/e2e-*.png' -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:-1:-1" -c:v libx264 -pix_fmt yuv420p /tmp/report.mp4

Decision Tree

Problem	Solution
Widget not found	Re-snapshot, try scrolling, check if on wrong screen, match by bounds position
Ref expired between commands	Use press x y with coordinates from last snapshot bounds, or press @ref --adb
System dialog blocking (location, permissions)	agent-flutter dismiss — detects and dismisses via ADB
"No isolate with Marionette"	ADB foreground + disconnect + reconnect
Snapshot returns 0 interactive elements	Marionette lost widget tree — disconnect then connect to re-attach
Bottom nav tabs not detected	back until nav bar appears, filter InkWell y > 780
Hot restart breaks connection	Wait 3s → disconnect → connect
Text labels null	Match by type, flutterType, or bounds — Marionette doesn't extract child text
Non-English IME breaks text input	Set system locale to English: adb shell "settings put system system_locales en-US"

iOS Simulator Known Limitations

Issue	Workaround
ASWebAuthenticationSession blocks Google Sign-In (system dialog, not automatable)	Use FirebaseAuth.instance.signInWithCustomToken(token) via VM Service evaluate
agent-flutter scroll fails (uses ADB/transport.swipe, Simulator window disconnected)	Scroll via VM Service Dart evaluation: pos.jumpTo() on Scrollable widgets
Simulator.app window shows Home Screen (not app) when booted via SSH user	Use simctl screenshot for true device state; use Marionette/VM Service for interaction
No simctl touch/swipe API	VM Service evaluate for Flutter-level interaction; cliclick only works if Simulator window is synced
iOS keychain persists through app uninstall	xcrun simctl erase <UDID> for full reset
iOS onboarding is shorter than Android (language only → home)	Mark skipped steps as pass with platform note

VM Service scroll expression (target app root library):

(() { var count = 0; void visit(Element el) { if (el.widget is Scrollable) { try { final s = (el as StatefulElement).state as ScrollableState; final p = s.position; if (p.maxScrollExtent > 0 && p.pixels < p.maxScrollExtent) { p.jumpTo((p.pixels + 500).clamp(0.0, p.maxScrollExtent)); count++; } } catch (_) {} } el.visitChildren(visit); } WidgetsBinding.instance.rootElement?.visitChildren(visit); return count; })()

iOS simulator auth (dev Firebase tokens rejected by prod API — needs local backend):

# .dev.env must point to a local/dev backend
API_BASE_URL=http://<your-backend-host>:<port>/
USE_WEB_AUTH=false
USE_AUTH_CUSTOM_TOKEN=true
# Regenerate envied after .dev.env change, rebuild app

Guard Conditions

NEVER:

• Use development env vars to bypass auth — test with real auth flows
• Set hasCompletedOnboarding to skip onboarding — test the real flow
• Modify source code to make tests pass — report the failure instead
• Commit screenshots to git — use GCS upload for PR evidence
