 Clone this repo.
 
-You have to install [melos](https://github.com/invertase/melos).
+```shell

+
+```shell

+```
+
+- genhtml. Used to convert coverage data into html pages.
+
+After installing all these packages, bootstrap with `melos bs`.
 
 ### Create a new package
 
 Create a new package in `packages/` folder.
 
 ```shell
-dart create -t package-simple wyatt_<name>
+mason make wyatt_package --package_name  wyatt_<name> --description A new Wyatt package --flutter_only false

+When you have finished developing, and are ready to close the issue, close it via your commit :

+`feat(auth): add AWS support. (close #31)`

+Note that your issue will be close after merging on master.
+Before closing the issue, please check tests and update coverage. You might run :
+
+```shell
+melos run test
+melos run gen_coverage
+```
+
+#### Merge your work
+
+After closing your issue, some work may have been done on master in the meantime. To keep a clean git history, please rebase before opening a change request.
+
+Two situations :

+- You have not yet created your branch and have committed locally :

+
+If possible, please use `--fixup` on your commit in interactive rebase.
+
+Then, opend your PR, get the necessary approval and merge your work. Then you're done ✅.
+
+#### Update version.
+
+Once your work is on the master, you can update your package version. Please filter packages to update only your package. `--scope` is used to do it.
+For example, after merging changes on `wyatt_otification_bloc` package, you might run :

+```shell
+melos version --scope="*wyatt_notification_bloc*"
+```

+
+Then create the data sources by extending `BaseLocalDataSource` or `BaseRemoteDataSource` depending the type of data source.
+
+```dart
+abstract class PhotoRemoteDataSource extends BaseRemoteDataSource {
+  Future<Photo> getPhoto(int id);
+  Future<List<Photo>> getAllPhotos({int? start, int? limit});
+}
+
+```
+
+Then you can create your repositories by extenting `BaseRepository` :
+
+```dart
+abstract class PhotoRepository extends BaseRepository {
+  FutureResult<Photo> getPhoto(int id);
+  FutureResult<List<Photo>> getAllPhotos({int? start, int? limit});
+}
+```
+
+> Here the repository is just a proxy of the data sources with result type (to have beautiful error handling).
+
+And finaly create your different usecases :
+
+Several use cases are supported :
+
+- Classic usecase :
+
+```dart
+class Test extends AsyncUseCase<QueryParameters, List<Photo>>> {
+
+  @override
+  FuturOrResult<List<Photo>>> call(QueryParameters? params) {
+     final photos = _photoRepository.getAllPhotos(
+      start: params.start,
+      limit: params.limit,
+    );
+    return photos;
+  }
+}
+```
+
+You can add alternatve scenarios and check pre/post conditions using our extensions :
+
+```dart
+class SearchPhotos extends AsyncUseCase<QueryParameters, List<Photo>>> {
+
+  @override
+  FutureOrResult<List<Photo>>> call(QueryParameters? params) {
+     final photos = _photoRepository.getAllPhotos(
+      start: params.start,
+      limit: params.limit,
+    );
+    return photos;
+  }
+
+
+  @override
+  FutureOr<void> onStart(QueryParameters? params) {
+    if(params.start == null || params.limit == null){
+      throw ClientException('Préconndition non valides');
+    }
+  }
+
+}
+```
+
+You can implement error scenarios overriding `onError`, or check postconditions by overriding `onComplete` .
+
+- Stream usecase :
+
+```dart
+class SearchPhotos extends StreamUseCase<QueryParameters, List<Photo>>> {
+
+  @override
+  FutureOrResult<Stream<List<Photo>>>> call(QueryParameters? params) {
+     final photos = _photoRepository.getAllPhotos(
+      start: params.start,
+      limit: params.limit,
+    );
+    return photos;
+  }
+
+}
+```
+
+On this case, observers allow you to add alternative scénarios when data changed, overriding `onData` or `onDone`.
+
+Please note that to use handlers, call `call` method and not `execute`.
+
+> In fact, here we need a new parameter object, so let's create it:
+
+```dart
+class QueryParameters {
+  final int? start;
+  final int? limit;
+
+  QueryParameters(this.start, this.limit);
+}
+```
+
+### Data
+
+We start by creating models for photos and list of photos. You can use `freezed`. The `PhotoModel` extends `Photo` with some de/serializer capabilities. And those are used only in data layer.
+
+Then implements your data sources:
+
+```dart
+class PhotoApiDataSourceImpl extends PhotoRemoteDataSource {
+  final MiddlewareClient _client;
+
+  PhotoApiDataSourceImpl(this._client);
+
+  @override
+  Future<Photo> getPhoto(int id) async {
+    final response = await _client.get(Uri.parse('/photos/$id'));
+    final photo =
+        PhotoModel.fromJson(jsonDecode(response.body) as Map<String, Object?>);
+    return photo;
+  }
+
+  @override
+  Future<List<Photo>> getAllPhotos({int? start, int? limit}) async {
+    final startQuery = start.isNotNull ? '_start=$start' : '';
+    final limitQuery = limit.isNotNull ? '_limit=$limit' : '';
+    final delimiter1 =
+        (startQuery.isNotEmpty || limitQuery.isNotEmpty) ? '?' : '';
+    final delimiter2 =
+        (startQuery.isNotEmpty && limitQuery.isNotEmpty) ? '&' : '';
+    final url = '/photos$delimiter1$startQuery$delimiter2$limitQuery';
+    final response = await _client.get(Uri.parse(url));
+    final photos =
+        ListPhotoModel.fromJson({'photos': jsonDecode(response.body)});
+    return photos.photos;
+  }
+}
+```
+
+> 1: Note that here we use `MiddlewareClient` from our http package.
+
+> 2: You can create multiple implementations (one real and one mock for example).
+
+And implement the repositories:
+
+```dart
+class PhotoRepositoryImpl extends PhotoRepository {
+  final PhotoRemoteDataSource _photoRemoteDataSource;
+
+  PhotoRepositoryImpl(
+    this._photoRemoteDataSource,
+  );
+
+  @override
+  FutureResult<Photo> getPhoto(int id) => Result.tryCatchAsync(
+        () => _photoRemoteDataSource.getPhoto(id),
+        (error) => ServerException('Cannot retrieve photo $id.'),
+      );
+
+  @override
+  FutureResult<List<Photo>> getAllPhotos({int? start, int? limit}) async =>
+      Result.tryCatchAsync(
+        () => _photoRemoteDataSource.getAllPhotos(start: start, limit: limit),
+        (error) => ServerException('Cannot retrieve all photos.'),
+      );
+}
+```
+
+That's all.

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
