# cherrypick # Quick start
Experimental development of DI in the Dart language ## Main components DI
### Binding
Binding is a custom instance configurator that contains methods for configuring a dependency.
There are two main methods for initializing a custom instance `toInstance()` and `toProvide()` and auxiliary `withName()` and `singleton()`.
`toInstance()` - takes a initialized instance
`toProvide()` - takes a `provider` function (instance constructor)
`withName()` - takes a string to name the instance. By this name, it will be possible to extract instance from the DI container
`singleton()` - sets a flag in the Binding that tells the DI container that there is only one dependency.
Example:
```dart
// initializing a text string instance through a method toInstance()
Binding<String>().toInstance("hello world");
// or
// initializing a text string instance
Binding<String>().toProvide(() => "hello world");
// initializing an instance of a string named
Binding<String>().withName("my_string").toInstance("hello world");
// or
Binding<String>().withName("my_string").toProvide(() => "hello world");
// instance initialization like singleton
Binding<String>().toInstance("hello world");
// or
Binding<String>().toProvide(() => "hello world").singleton();
```
### Module
Module is a container of user instances, and on the basis of which the user can create their modules. The user in his module must implement the `void builder (Scope currentScope)` method.
Example:
```dart
class AppModule extends Module {
@override
void builder(Scope currentScope) {
bind<ApiClient>().toInstance(ApiClientMock());
}
}
```
### Scope
Scope is a container that stores the entire dependency tree (scope, modules, instances).
Through the scope, you can access the custom `instance`, for this you need to call the `resolve<T>()` method and specify the type of the object, and you can also pass additional parameters.
Example:
```dart
// open main scope
final rootScope = Cherrypick.openRootScope();
// initializing scope with a custom module
rootScope.installModules([AppModule()]);
// takes custom instance
final str = rootScope.resolve<String>();
// or
final str = rootScope.tryResolve<String>();
// close main scope
Cherrypick.closeRootScope();
```
## Example app
```dart
import 'dart:async';
import 'package:meta/meta.dart';
import 'package:cherrypick/cherrypick.dart';
class AppModule extends Module {
@override
void builder(Scope currentScope) {
bind<ApiClient>().withName("apiClientMock").toInstance(ApiClientMock());
bind<ApiClient>().withName("apiClientImpl").toInstance(ApiClientImpl());
}
}
class FeatureModule extends Module {
bool isMock;
FeatureModule({required this.isMock});
@override
void builder(Scope currentScope) {
bind<DataRepository>()
.withName("networkRepo")
.toProvide(
() => NetworkDataRepository(
currentScope.resolve<ApiClient>(
named: isMock ? "apiClientMock" : "apiClientImpl",
),
),
)
.singleton();
bind<DataBloc>().toProvide(
() => DataBloc(
currentScope.resolve<DataRepository>(named: "networkRepo"),
),
);
}
}
void main() async {
final scope = openRootScope().installModules([
AppModule(),
]);
final subScope = scope
.openSubScope("featureScope")
.installModules([FeatureModule(isMock: true)]);
final dataBloc = subScope.resolve<DataBloc>();
dataBloc.data.listen((d) => print('Received data: $d'),
onError: (e) => print('Error: $e'), onDone: () => print('DONE'));
await dataBloc.fetchData();
}
class DataBloc {
final DataRepository _dataRepository;
Stream<String> get data => _dataController.stream;
StreamController<String> _dataController = new StreamController.broadcast();
DataBloc(this._dataRepository);
Future<void> fetchData() async {
try {
_dataController.sink.add(await _dataRepository.getData());
} catch (e) {
_dataController.sink.addError(e);
}
}
void dispose() {
_dataController.close();
}
}
abstract class DataRepository {
Future<String> getData();
}
class NetworkDataRepository implements DataRepository {
final ApiClient _apiClient;
final _token = 'token';
NetworkDataRepository(this._apiClient);
@override
Future<String> getData() async => await _apiClient.sendRequest(
url: 'www.google.com', token: _token, requestBody: {'type': 'data'});
}
abstract class ApiClient {
Future sendRequest({@required String url, String token, Map requestBody});
}
class ApiClientMock implements ApiClient {
@override
Future sendRequest(
{@required String? url, String? token, Map? requestBody}) async {
return 'Local Data';
}
}
class ApiClientImpl implements ApiClient {
@override
Future sendRequest(

return 'Network data';
}
}
