Overview
The mime package provides utilities for working with MIME types in Dart and Flutter applications. It enables developers to determine the appropriate MIME type from a file extension or by inspecting file contents, which is essential for handling file uploads, HTTP requests, and content negotiation. The package supports a wide range of file types and integrates seamlessly across all major platforms including Android, iOS, Web, macOS, Windows, and Linux. It is particularly useful in scenarios involving file processing, server communication, and media handling.
