Usage #
Vault #
The example bellow creates a vault with a in-memory storage backend.
import 'package:stash/stash_api.dart';
import 'package:stash_memory/stash_memory.dart';

class Task {
final int id;
final String title;
final bool completed;

Task({required this.id, required this.title, this.completed = false});

@override
String toString() {
return 'Task $id, "$title" is ${completed ? "completed" : "not completed"}';
}
}

void main() async {
// Creates a store
final store = await newMemoryVaultStore();

// Creates a vault from the previously created store
final vault = await store.vault<Task>(
name: 'vault', eventListenerMode: EventListenerMode.synchronous)
..on<VaultEntryCreatedEvent<Task>>().listen(
(event) => print('Key "${event.entry.key}" added to the vault'));

// Adds a task with key 'task1' to the vault
await vault.put(
'task1', Task(id: 1, title: 'Run vault store example', completed: true));
// Retrieves the value from the vault
print(await vault.get('task1'));
}

Cache #
The example bellow creates a cache with a in-memory storage backend.
import 'package:stash/stash_api.dart';
import 'package:stash_memory/stash_memory.dart';

class Task {
final int id;
final String title;
final bool completed;

Task({required this.id, required this.title, this.completed = false});

@override
String toString() {
return 'Task $id, "$title" is ${completed ? "completed" : "not completed"}';
}
}

void main() async {
// Creates a store
final store = await newMemoryCacheStore();

// Creates a cache with a capacity of 10 from the previously created store
final cache = await store.cache<Task>(
name: 'cache1',
maxEntries: 10,
eventListenerMode: EventListenerMode.synchronous)
..on<CacheEntryCreatedEvent<Task>>().listen(
(event) => print('Key "${event.entry.key}" added to the cache'));

// Adds a task with key 'task1' to the cache
await cache.put(
'task1', Task(id: 1, title: 'Run cache store example', completed: true));
// Retrieves the value from the cache
print(await cache.get('task1'));
