Flutter Error Handling

What problem does it solve?

This Skill addresses the challenge of managing errors and exceptions in Flutter applications by enforcing a standardized, functional approach, preventing raw exceptions from reaching the UI.

Core Features & Use Cases

• Standardized Error Handling: Implements the Either pattern for predictable error propagation.
• Domain-Specific Failures: Utilizes @freezed unions for clear, typed error representations.
• Use Case: Ensure that all data fetching operations return Either<Failure, Data>, allowing BLoCs to gracefully handle network issues, server errors, or authentication failures without crashing.

Quick Start

Implement functional error handling by returning Either<Failure, T> from repositories and using .fold() in BLoCs.
