# CherryPick Flutter # CherryPick Flutter
`cherrypick_flutter` is a powerful Flutter library for managing and accessing dependencies within your application through a root scope context using `CherryPickProvider`. It offers simplified dependency injection, making your application more modular and test-friendly. `cherrypick_flutter` is a robust Flutter library designed for managing and accessing dependencies using a scope context provided by `CherryPickProvider`. It enhances your application's modularity and testability by simplifying dependency injection.
## Quick Start ## Quick Start
### Main Components in Dependency Injection (DI) ### Core Components of Dependency Injection (DI)
#### Binding #### Binding
A Binding is a custom instance configurator, essential for setting up dependencies. It offers the following key methods: A Binding is a custom instance configurator crucial for setting up dependencies. It offers the following key methods:
- `toInstance()`: Directly provides an initialized instance. - `toInstance()`: Directly provides an initialized instance.
- `toProvide()`: Accepts a provider function or constructor for lazy initialization. - `toProvide()`: Accepts a provider function for lazy initialization.
- `withName()`: Assigns a name to an instance, allowing for retrieval by name. - `toProvideAsync()`: Accepts an asynchronous provider for lazy initialization.
- `singleton()`: Marks the instance as a singleton, ensuring only one instance exists in the scope. - `toProvideWithParams()`: Accepts a provider function requiring dynamic parameters.
- `toProvideAsyncWithParams()`: Accepts an asynchronous provider requiring dynamic parameters.
- `withName()`: Assigns a name for instance retrieval by name.
- `singleton()`: Marks the instance as a singleton, ensuring only one instance exists within the scope.
##### Example: ##### Example:
```dart ```dart
// Direct instance initialization with toInstance() // Direct instance initialization using toInstance()
Binding<String>().toInstance("hello world"); Binding<String>().toInstance("hello world");
// Or use a provider for lazy initialization // Lazy initialization via provider
Binding<String>().toProvide(() => "hello world"); Binding<String>().toProvide(() => "hello world");
// Named instance // Asynchronous lazy initialization
Binding<String>().withName("my_string").toInstance("hello world"); Binding<String>().toProvideAsync(() async => "hello async world");
/ Asynchronous lazy initialization with dynamic parameters
Binding<String>().toProvideAsyncWithParams((params) async => "hello $params");
// Initialization with dynamic parameters
Binding<String>().toProvideWithParams((params) => "hello $params");
// Named instance for resolution
Binding<String>().toProvide(() => "hello world").withName("my_string").toInstance("hello world");
// Singleton instance // Singleton instance
