Custom Error Management for Dart

The "custom_error" library is a powerful Dart package designed to streamline error management and elevate error handling in your Dart applications. This package offers a single class, Error, which empowers developers to create, store, and access custom error instances with ease. Key features of the "custom_error" package include:

Features

• Custom Error Management: The Error class allows you to create and manage custom error objects with both error codes and messages. This is particularly valuable for precise error tracking within your application.

• Flexible Error Storage: The library includes a list of maps to store error details, enabling you to accumulate multiple errors and access them as needed.

• Error Retrieval: Convenient getter methods, such as getError() and getErrorCode(), facilitate easy access to individual error details.

• Comprehensive Error Access: The getAllErrors() method enables you to access the entire list of errors, making it helpful for debugging and reporting.

• Type Checking: The isAnError() method allows you to determine whether a given value is an instance of the Error class.
