Unhandled Exception: UnimplementedError: idbFactoryNative

[saintjab]

I am getting the error as in title. Running this in Android emulator. This is my code:

const storeName = "myStrore";
final idbFactory = getIdbFactory("native");
late Database database;

void initStore() async {
  database = await getDatabase(idbFactory!);
}

Future<Database> getDatabase(IdbFactory idbFactory) async {
  final db = await idbFactory.open('store.db', version: 1,
      onUpgradeNeeded: (VersionChangeEvent event) {
        final db = event.database;
        db.createObjectStore(storeName, autoIncrement: true);
      });
  return db;
}

then calling the initStore() in main.dart file. Am using the latest version (2.6.1+7) of the lib

The native factory (idbFactoryWeb) is only available on the web. I'm assuming you are using flutter. If you want to target Android, while idbFactoryIo could work I would recommend using idb_sqflite.

The recommended implementation is idb_sqflite
based on sqflite for mobile (iOS, MacOS and Android) or desktop and dart VM using sqflite_ffi_common.

Choosing an implementation is mainly finding the best IdbFactory for the platform.

Here is a basic example to target both web and mobile

In pubspec.yaml:

dependencies:
  idb_shim: any
  idb_sqflite: any

import 'package:flutter/foundation.dart';
import 'package:flutter/widgets.dart';
import 'package:idb_sqflite/idb_sqflite.dart';

late IdbFactory idbFactory;

/// Initialization example for flutter
///
/// It uses indexed_db on the web and sqflite on other platforms
void initIdbFactory() {
  WidgetsFlutterBinding.ensureInitialized();
  if (kIsWeb) {
    idbFactory = idbFactoryWeb;
  } else {
    idbFactory = idbFactorySqflite;
  }
}
