Navigation
App Flow
The app follows this general flow:
Launch → Scanner Screen → [Connect via BLE/USB/TCP] → Channels Screen
After connecting, the three main screens (Contacts, Channels, Map) are accessible via a persistent bottom navigation bar called the QuickSwitchBar.
Quick Switch Bar
The QuickSwitchBar is a Material 3 NavigationBar with a frosted-glass visual treatment (blur backdrop, transparent theme, rounded corners). It appears at the bottom of all three main screens.
| Index | Icon | Label | Screen |
|---|---|---|---|
| 0 | People | Contacts | ContactsScreen |
| 1 | Tag | Channels | ChannelsScreen |
| 2 | Map | Map | MapScreen |
Tapping a tab replaces the current screen with a subtle fade + slight horizontal nudge transition (220ms forward, 200ms reverse). The back button is suppressed on all three main screens — navigation between them is flat, not stacked. All icons use outline variants (people_outline, tag, map_outlined) following Material 3 conventions.
Disconnection
- The disconnect button (available in the overflow menu of each main screen) shows a confirmation dialog before disconnecting
- If the device disconnects unexpectedly, the app automatically navigates back to the Scanner screen (fires after the current frame completes via a post-frame callback)
- This auto-navigation behavior (
DisconnectNavigationMixin) is shared across all main screens
Theme and Locale
- Theme mode is user-configurable in App Settings (System / Light / Dark) — not locked to system
- Language can be overridden to one of 18 supported languages, or follow the system locale
- On web, if a non-Chromium browser is detected, the app shows a
ChromeRequiredScreeninstead of the Scanner (Web Bluetooth requires Chromium)
