Last year during the Fluttercon session about future of native interop I learned about this new tool called jnigen. It's became quite stable recently and I wanted to try it out again. Some background In the past I used Xamarin and back then it was quite natural to invoke platform APIs from C# through something called bindings. In other words classes like Activity, Context, NSUrl, UIView were accessible directly from C# without any additional glue code. It was also possible with a bit of work to expose most of the native libraries in a similar fashion. Sort of similar thing…

Building a Robust Local Storage Service in Flutter

stp2y0 CommentsNewscoding, community, dart, development, engineering, flutter, inclusive, mobile, software, tutorial

Modern mobile applications often need to store various types of data locally - from user preferences to authentication tokens. While Flutter provides SharedPreferences for basic storage and FlutterSecureStorage for encrypted storage, managing these effectively in a large application requires careful architectural planning. In this article, we'll explore how to build a robust key-value storage system that separates concerns, provides type safety, and makes storage operations maintainable and secure. The Two-Layer Architecture Our implementation uses a two-layer architecture: KeyValueStorageBase: A low-level base class that directly interfaces with storage plugins KeyValueStorageService: A high-level service that provides typed, domain-specific storage operations Why Two…
