# Flutter + SQLite
 [![License (MIT)][licence-image]][licence-url]
This repository contains a simple [Flutter](https://flutter.dev/) application that manages contact information using [SQLite](https://www.sqlite.org/index.html) (via [SQFLite](https://pub.dev/packages/sqflite)).
## Requirements
To run this application be sure to check out [the Flutter documentation](https://docs.flutter.dev/get-started/install) for getting started.
## Key takeaways
To use SQLite within a Flutter application you're going to need to add a couple dependencies to the [pubspec.yaml](src/pubspec.yaml) file.
> Note: The [Dart](dart.dev) ecosystem uses packages to manage shared software such as libraries and tools. To get Dart packages, you use the pub package manager. Find more information on Dart package management [here](https://dart.dev/guides/packages).
More specifically, the [sqflite](https://pub.dev/packages/sqflite) and [path_provider](https://pub.dev/packages/path_provider) packages are required.
```yaml
dependencies:
flutter:
sdk: flutter
sqflite: any
path_provider: any
```
From there a SQLite database (and tables) can be created and used within the application.
For this applicaiton I have put all of the SQFLite usages within [database_helper.dart](src/lib/data/database_helper.dart).
```dart
import 'dart:async';
import 'dart:io' as io;
import 'package:path/path.dart';
import 'package:path_provider/path_provider.dart';
import 'package:rolodex/models/base_model.dart';
import 'package:sqflite/sqflite.dart';
class DatabaseHelper {
static final DatabaseHelper _instance = DatabaseHelper.internal();
factory DatabaseHelper() => _instance;
static Database? _db;
Future get db async {
_db ??= await init();
return _db!;
}
DatabaseHelper.internal();
Future init() async {
io.Directory documentsDirectory = await getApplicationDocumentsDirectory();
String path = join(documentsDirectory.path, "main.db");
return openDatabase(path, version: 1, onCreate: onCreate);
}
void onCreate(Database db, int version) async =>
await db.execute('CREATE TABLE contacts (id INTEGER PRIMARY KEY NOT NULL, firstName STRING, lastName STRING, phone STRING, email STRING)');
Future>> query(String table) async => (await db).query(table);
Future insert(String table, BaseModel model) async => (await db).insert(table, model.toMap());
Future update(String table, BaseModel model) async => (await db).update(table, model.toMap(), where: 'id = ?', whereArgs: [model.id]);
Future delete(String table, BaseModel model) async => (await db).delete(table, where: 'id = ?', whereArgs: [model.id]);
}
```
