op_result 0.3.1

A generic result type for handling success and error cases in a type-safe manner.

OpResult

A lightweight, type-safe result wrapper for handling success and failure cases in Dart.

Features

OpResult is a generic class designed to handle operations that return either a success or a failure in a structured and type-safe manner.

• Generic over Success Type (OpResult<T>) — errors are wrapped using OpError with enum types
• Prevents null checks—ensures only one of data or error exists
• Encapsulates errors in a structured way using enums
• Easily maps error types to custom/multi-language messages
• Works seamlessly in any context, with APIs, validation, domain logic, etc.
• No dependencies—lightweight and efficient
