Overview
json_cache is a Dart package that provides an object-oriented approach to locally caching user data in JSON format. Built as a flexible layer on top of existing local storage solutions, it unifies their interfaces for consistent use across platforms. The package simplifies data persistence by handling serialization and deserialization automatically, making it easy to store and retrieve complex objects. Designed for simplicity and interoperability, it supports Android, iOS, macOS, Windows, and Linux, enabling seamless cross-platform data caching with minimal boilerplate.
