A package to help handle Cubit instances across the app.

Get Cubit

A package to help handle Cubit instances across the app.

• Register a singleton instance of a cubit and access across the app
• Register multiple instances of a cubit using unique identifiers
• Easily handle cubit to cubit communications

Installation

To use this package, add get_cubit to your pubsec.yaml file.

or run the below command

pub add get_cubit

Usage

example of cubit :

class CounterCubit extends Cubit<int> {
  CounterCubit() : super(0);

  void increment() => emit(state + 1);
  void decrement() => emit(state - 1);
}

Registering a cubit instance

To register an instance of the CounterCubit class

// register a new instance
GetCubit().put(CounterCubit());

// register an existing instance
CounterCubit counterCubit = CounterCubit();
GetCubit().put(counterCubit);

// another way to register an existing instance
counterCubit.addInstanceToGetCubit<CounterCubit>();

Creating multiple instances using unique identifiers

// register a new instance with id
GetCubit().put(CounterCubit(), id : "cubit_1");
GetCubit().put(CounterCubit(), id : "cubit_2");

// register an existing instance with id
CounterCubit counterCubit1 = CounterCubit();
CounterCubit counterCubit2 = CounterCubit();
GetCubit().put(counterCubit1, id : "cubit_1");
GetCubit().put(counterCubit1, id : "cubit_2");

// another way to register an existing instance with id
counterCubit1.addInstanceToGetCubit<CounterCubit>(id : "cubit_1");
counterCubit2.addInstanceToGetCubit<CounterCubit>(id : "cubit_2");

Accessing the registered instances

The registered instances can be accessed using GetCubit().find()

// file_1.dart :
final CounterCubit counterCubit = GetCubit().put(CounterCubit());
print(counterCubit.state); // 0
counterCubit.increment();

// file_2.dart
print(GetCubit().find<CounterCubit>().state); // 1

Accessing the registered instances using id

// file_1.dart :
final CounterCubit counterCubit1 = GetCubit().put(CounterCubit(), id : "cubit_1");
final CounterCubit counterCubit2 = GetCubit().put(CounterCubit(), id : "cubit_2");
counterCubit1.emit(5);
counterCubit2.emit(10);

// file_2.dart
print(GetCubit().find<CounterCubit>(id : "cubit_1").state); // 5
print(GetCubit().find<CounterCubit>(id : "cubit_2").state); // 10

deleting a registered instance

 GetCubit().delete<CounterCubit>(); // without id
 GetCubit().delete<CounterCubit>(id : "cubit_1"); // with id

deleting all the registered instances linked of a cubit

GetCubit().find<CounterCubit>().deleteAllInstances();

Listing all the unique ids linked to instances of a cubit

GetCubit().put(CounterCubit(),id : "c1");
GetCubit().put(CounterCubit(),id : "c2");
GetCubit().put(CounterCubit(),id : "c3");
GetCubit().put(CounterCubit(),id : "c4");
GetCubit().put(CounterCubit(),id : "c5");

List<String> ids = GetCubit().find<CounterCubit>().getAllInstanceIds();
print(ids); // [c1,c2,c3,c4,c5]
