Barbarian

Barbarian is a fast and simple way to save data in NoSQL. It is a simple wrap of Shared preferences.

Initialize Barbarian

await Barbarian.init();

Save

Save any object, Map, List, HashMap etc. including all internal objects. Use your existing data classes as is.

Barbarian.write('string', 'cadena');
Barbarian.write('bool', true);
Barbarian.write('integer', 7);
Barbarian.write('double', 3.8);

Read

Read data objects is as easy as

String str = Barbarian.read('string');
bool boole = Barbarian.read('bool');
int ibtg = Barbarian.read('integer');
double doub = Barbarian.read('double');

Delete

Delete data for one key.

Barbarian.delete('string');

Remove all keys

Barbarian.destroy();

Get all keys

Returns all keys for objects in the book.

List<String> allKeys = Barbarian.getAllKeys();

Complex data

To save an object it is important that it has some form of serialization. Like this

class Item {
  int id;
  String name;
  List<String> locations;
  double price;
  int stock;
  bool active;

  Item(
      {this.id,
      this.name,
      this.locations,
      this.price,
      this.stock,
      this.active});

  Map<String, dynamic> toJson() => {
        'id': id,
        'name': name,
        'locations': locations,
        'price': price,
        'stock': stock,
        'active': active
      };

  Item.fromMap(Map<String, dynamic> map)
      : id = map['id'],
        name = map['name'],
        locations = List<String>.from(map['locations']),
        price = map['price'],
        stock = map['stock'],
        active = map['active'];

  @override
  String toString() => toJson().toString();
}

Save

Barbarian.write('item', item);

Read

Item oldItem = Barbarian.read('item', customDecode: (output) => Item.fromMap(output));
