Getting Started

1. Calling WidgetsFlutterBinding.ensureInitialized(); in main() before calling runApp():

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp());
}

2. Import import 'package:localstore/localstore.dart';

import 'package:flutter/material.dart';
import 'package:localstore/localstore.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  runApp(MyApp());
}

3. Creates an instance using the default Localstore

final db = Localstore.instance;

or using anywhere in your project.

4. Creates new item

// gets new id
final id = db.collection('todos').doc().id;

// save the item
db.collection('todos').doc(id).set({
  'title': 'Todo title',
  'done': false
});

5. Gets item by id

final data = await db.collection('todos').doc(id).get();

6. Delete item by id
