Building from Source

Prerequisites

• Flutter SDK 3.8.1+
• A Jellyfin server

Setup

git clone https://github.com/edde746/jellzy.git
cd jellzy
flutter pub get
dart run build_runner build
flutter run

Branded Build (Fixed Server URL)

To build a version that always connects to a specific Jellyfin server:

flutter run --dart-define=JELLYFIN_SERVER_URL=https://your-jellyfin-server.com

When built with JELLYFIN_SERVER_URL, the app skips the server URL input screen and goes directly to the login form for that server.

Code Generation

After modifying model classes:

dart run build_runner build --delete-conflicting-outputs
