dorm_example is a command-line generator for complete dORM showcase projects. It creates the annotated source, generated-code commands, application flow, and backend configuration for one selected engine.

Install the generator

Install the executable globally:

dart pub global activate dorm_example

Check the available options:

dorm_example --help

The CLI uses colors in interactive terminals and omits them in redirected output. Use --no-color or set NO_COLOR when plain output is preferred.

Generate a project

Choose one engine and, optionally, an output directory. Without --output, the directory name defaults to the selected engine:

dorm_example --engine memory
dorm_example --engine postgres --output store_example

For example, dorm_example --engine memory creates memory/. The output directory must be empty or must not exist. The generator does not overwrite existing files, run pub get, run build_runner, start Docker, or start the generated application.

Generated profiles

Profile Application Infrastructure
in-memory Flutter Web None
bloc Flutter Web None
firebase Flutter Web Firebase Emulator Suite
firestore Flutter Web Firebase Emulator Suite
http Flutter Web Local Dart HTTP server
postgres Pure Dart PostgreSQL in Docker Compose
mysql Pure Dart MySQL in Docker Compose
mongo Pure Dart MongoDB in Docker Compose
sqlite Pure Dart Local SQLite file

All profiles use the same store domain with users, products, categories, carts, cart items, wishlists, and reviews. SQL profiles keep the model surface portable and avoid JSON-specific annotations such as ModelField, PolymorphicField, and DerivedField.

Run a generated project

After generation, enter the output directory and follow the generated README. A typical pure Dart profile uses:

cd store_example
docker compose up -d
dart pub get
dart run build_runner build
dart analyze
dart run

A Flutter profile uses:

cd store_example
flutter pub get
dart run build_runner build
flutter analyze
flutter run -d chrome

Flutter profiles require Flutter 3.47.1 or newer. Pure Dart profiles do not have this Flutter requirement.

Docker Compose starts infrastructure only. The Dart or Flutter application runs on the host so that local environment variables, browser access, and Flutter development tools remain available.

Backend configuration

  • PostgreSQL, MySQL, and MongoDB generate Docker Compose files, environment templates, and backend-specific startup instructions.
  • SQLite generates sql/schema.sql and reads that rendered file when the application starts.
  • Firebase and Firestore generate local Firebase Emulator configuration.
  • HTTP generates a local in-memory Dart server and a configured HttpMapping.
  • The in-memory and BLoC profiles run without an external service.

The generated .env.example file documents required variables. It is a reference file; the generated application does not load it automatically.

Modify the showcase

Edit the generated lib/models.dart file when changing models. Then regenerate the model API:

dart run build_runner build --delete-conflicting-outputs

The generated *.dorm.dart and *.g.dart files are derived output. Keep the annotated source as the file you edit.

Troubleshooting

  • A non-empty output directory fails by design; choose another path or remove only the generated directory.
  • A missing generated API means build_runner has not been run in the project root.
  • A database profile cannot connect until its Compose service is running and its environment values match the generated configuration.
  • A Flutter profile needs Flutter and a browser target installed.
  • The HTTP profile requires its generated http-api service to be running.
