Connect the apps to your server

Each app reads your server’s address from one file: lib/app_config.dart. Set it once per app before you run or build it.

App	File
Customer	apps/customer/lib/app_config.dart
Seller	apps/seller/lib/app_config.dart
Rider	apps/delivery/lib/app_config.dart

Set the address

1. Open the app’s lib/app_config.dart in any editor (Android Studio, VS Code …).
2. Put your address between the quotes on the baseUrl line:

   apps/customer/lib/app_config.dart

   static const String baseUrl = 'https://yourdomain.com';

   Use the same address as your website and admin — the Site URL you entered in the installer — with https:// and no trailing slash.
3. Save, then do the same in the other two apps.

All three apps

Set it in the customer, seller and rider app. An app with an empty baseUrl looks for a server on the computer it was built on, and shows connection errors on real phones.

Check the connection

1. Run the customer app (flutter run in apps/customer).
2. The home screen should show your store name and brand colour (Settings → Brand & business) — the app downloads them from your server when it starts.
3. If it shows a connection error, open https://yourdomain.com/api/bootstrap in the phone’s browser: it should show text starting with {. If it doesn’t, the server or HTTPS isn’t reachable from the phone.

HTTPS only

Release builds only talk to https:// servers. Plain http:// works in debug builds, for testing against a server on your own computer — leave baseUrl empty and the app uses 127.0.0.1:8001 (or 10.0.2.2:8001 from the Android emulator).

Changing servers later

Edit baseUrl, then build and publish a new version of each app. Phones keep using the address their installed version was built with.
