SharedInbox

IMAP/SMTP email client written in Flutter.

Targets Android, iOS, and Desktop (Linux, macOS, Windows).
Supports multiple accounts — each synced independently via IMAP IDLE.

Design philosophy: offline-first

IMAP/SMTP server
       ↓
  AccountSyncManager  ←→  Drift (SQLite, local DB)
                                   ↓
                             UI (reads only from DB)

The UI never touches the network. The sync engine runs in the background and writes to a local Drift database. Screens observe reactive streams from that DB.
