  • Version: 1.0.2

Role in the stack

Koder Lex is the mobile front-end for law firms and solo attorneys. It provides case management, court tracking, deadline control, billing (with live timer), document management, client CRM, calendar scheduling, AI-powered legal research, contract lifecycle, compliance, and reporting — all in a single Flutter app.

The app talks to https://lex.koder.dev/api/v1 via LexApiService. Authentication uses Koder ID PKCE flow (dev.koder.lex client, registered in Koder ID). Tokens are stored in flutter_secure_storage; auto-refresh on 401.
