   Better than JSON

   Protocol Buffers (Protobuf) offers significant advantages over JSON for API development through strong typing, binary serialization, and automatic code generation. While JSON remains popular for its human readability and flexibility, Protobuf provides 3x smaller payload sizes, type safety across multiple languages, and eliminates manual validation errors. The article demonstrates practical implementation using Dart and the Shelf framework, showing how Protobuf can be used independently of gRPC in traditional HTTP APIs. The main trade-off is reduced human readability of binary data, requiring schema files and specialized tooling for debugging.

   Don't mix bloc with get_it

   Mixing Bloc with dependency injection tools like get_it requires careful consideration to avoid issues with state management. Using singletons for BLoC can disrupt its lifecycle, causing unexpected state persistence and errors. Instead, use registerFactory to ensure clean state instances. For better integration, use RepositoryProvider for dependencies within the widget tree.

    A New Era for App Design (and What it Means for Flutter)

    Flutter is decoupling Material and Cupertino UI libraries from its core SDK, moving them to independent packages on pub.dev. This change enables faster updates for UI components, gives developers more flexibility in choosing design systems, and creates equal opportunities for third-party UI libraries. The move positions Flutter as a more modular framework that can adapt to new design trends like Apple's Liquid Glass and Google's Material 3 Expressive without being constrained by SDK release cycles.
