Disposable

CherryPick can automatically clean up any dependency that implements the Disposable interface. This makes resource management (for controllers, streams, sockets, files, etc.) easy and reliable—especially when scopes or the app are shut down.

If you bind an object implementing Disposable as a singleton or provide it via the DI container, CherryPick will call its dispose() method when the scope is closed or cleaned up.

Key Points

• Supports both synchronous and asynchronous cleanup (dispose may return void or Future).
• All Disposable instances from the current scope and subscopes will be disposed in the correct order.
• Prevents resource leaks and enforces robust cleanup.
• No manual wiring needed once your class implements Disposable.

Minimal Sync Example

class CacheManager implements Disposable {
  void dispose() {
    cache.clear();
    print('CacheManager disposed!');
  }
}

final scope = CherryPick.openRootScope();
scope.installModules([
  Module((bind) => bind<CacheManager>().toProvide(() => CacheManager()).singleton()),
]);

// ...later
await CherryPick.closeRootScope(); // prints: CacheManager disposed!

Async Example

class MyServiceWithSocket implements Disposable {
  @override
  Future<void> dispose() async {
    await socket.close();
    print('Socket closed!');
  }
}

scope.installModules([
  Module((bind) => bind<MyServiceWithSocket>().toProvide(() => MyServiceWithSocket()).singleton()),
]);

await CherryPick.closeRootScope(); // awaits async disposal

Tip: Always call await CherryPick.closeRootScope() or await scope.closeSubScope(key) in your shutdown/teardown logic to ensure all resources are released automatically.
