flutter-databases

MVVM-compliant data layer for Flutter with Repository pattern, stateless Services, and intelligent local caching strategies. Architects and implements a robust, MVVM-compliant data layer in Flutter applications. Establishes a single source of truth using the Repository pattern, isolates external API and local database interactions into stateless Services, and implements optimal local caching strategies (e.g., SQLite via sqflite ) based on data requirements. Assumes a pre-configured Flutter environment. Evaluate the user's data persistence requirements using the following decision tree to select the appropriate caching strategy: Analyze Data Requirements STOP AND ASK THE USER: "What specific data entities need to be managed in the data layer, and what are their persistence requirements (e.g., size, relational complexity, offline-first capabilities)?" Wait for the user's response before proceeding to step 2. Configure Dependencies Based on the decision logic, add the required dependencies. For a standard SQLite implementation, execute: Define Domain Models Create pure Dart data classes representing the domain models. These models should contain only the information needed by the rest of the app.
