Pub Package Coverage Status Package Documentation GitHub License

Introduction #

This storage extension for stash provides a sembast based storage that relies on a highly performing binary serialization of the cache items through the use of msgpack serialization format.

Getting Started #

Add this to your pubspec.yaml (or create it):

dependencies:
    stash_sembast: ^2.0.0

Run the following command to install dependencies:

pub get

Optionally use the following command to run the tests:

pub run test

Finally, to start developing import the library:

import 'package:stash_sembast/stash_sembast.dart';

Usage #

This storage extension for stash provides a hive based storage that relies on a highly performing binary serialization of the cache items through the use of msgpack serialization format.

import 'dart:io';

import 'package:stash_sembast/stash_sembast.dart';

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

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

  /// Creates a [Task] from json map
  factory Task.fromJson(Map<String, dynamic> json) => Task(
      id: json['id'] as int,
      title: json['title'] as String,
      completed: json['completed'] as bool);

  /// Creates a json map from a [Task]
  Map<String, dynamic> toJson() =>
      <String, dynamic>{'id': id, 'title': title, 'completed': completed};

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

void main() async {
  // Temporary path
  final path = Directory.systemTemp.path;

  // Creates cache with a Sembast based storage backend with a maximum capacity of 10 entries
  final cache = newSembastCache(path,
      maxEntries: 10, fromEncodable: (json) => Task.fromJson(json));

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

  print(value);
}
