powersync_sqlcipher 0.1.0

PowerSync Flutter SDK - sync engine for building local-first apps.

PowerSync with SQLCipher SDK for Flutter

PowerSync is a sync engine for building local-first apps with instantly-responsive UI/UX and simplified state transfer. Syncs between SQLite on the client-side and Postgres, MongoDB or MySQL on the server-side.

This package (powersync_sqlcipher) is the PowerSync client SDK for Flutter with encryption enabled using SQLCipher. It is currently in a beta release. This means it is safe to use in production, provided that you've tested your use cases.

If you do not require encryption in your Flutter application, we recommend using the powersync SDK.

Installing PowerSync with SQLCipher encryption in your own project

Install the latest version of the package, for example:

flutter pub add powersync_sqlcipher

Version history can be found here.

Usage

This SDK requires a slightly different setup to the powersync package in order to encrypt the local database:

import 'package/powersync_sqlcipher/powersync.dart';

/// Global reference to the database
late final PowerSyncDatabase db;

final cipherFactory = PowerSyncSQLCipherOpenFactory(
      path: path, key: "sqlcipher-encryption-key"); // https://www.zetetic.net/sqlcipher/sqlcipher-api/#key

db = PowerSyncDatabase.withFactory(cipherFactory, schema: schema);
