Deploy a Dart application on onesubnet

onesubnet runs your Dart backends (shelf, dart_frog, custom servers). Deploy via Git.

1. Prepare the project

• A pubspec.yaml at the root.
• Listen on the port from the PORT variable:

final port = int.parse(Platform.environment['PORT'] ?? '8080');
final handler = (Request request) => Response.ok('Hello from Dart');
await serve(handler, InternetAddress.anyIPv4, port);

2. Deploy

1. Connect your Git repository in the panel.
2. Build command: dart pub get
3. Start command: dart run bin/server.dart (or dart_frog dev / dart_frog prod).

3. Environment variables

In Settings → Environment. Access via Platform.environment['...'].

4. Logs

Live console in the panel.
