Overview
form_bloc is a Flutter package that simplifies form state management by implementing the BLoC pattern. It separates form state and business logic from the UI, enabling clean, testable code. Supports asynchronous validation, loading states, dynamic fields, and seamless integration with Flutter's reactive architecture. Ideal for complex forms requiring real-time feedback and state persistence. The package is platform-agnostic, working across Android, iOS, Web, macOS, Windows, and Linux.
