In the context of mobile development with Flutter, choosing the right offline database solution involves evaluating factors such as ease of setup and operational speed. The article examines several database options, including Hive, Sembast, Sqflite, Isar, and ObjectBox, focusing on their ability to perform CRUD (Create, Read, Update, Delete) operations. It provides a detailed comparison through benchmarking tests on both iOS and Android devices, revealing that while setup processes are generally straightforward, performance varies significantly across databases. Hive stands out for its speed in reading operations on both platforms, Isar excels in write performance on iOS, and ObjectBox shows notable efficiency in delete operations on Android when optimized methods are used. The article concludes that the choice of database might ultimately depend on personal syntax preferences, noting that Hive offers a simple setup, while Isar and ObjectBox offer the advantage of interacting directly with Dart objects, albeit with additional setup requirements. For those interested in further exploration, a link to the GitHub project with the benchmark code is provided.
