Overview
Thumbnailer is a Flutter plugin that generates thumbnails from files of various MIME types, such as images, documents, and videos. When a file's MIME type does not support thumbnail generation, it returns a fallback icon. The plugin supports multiple platforms including Android, iOS, Web, macOS, and Windows, making it ideal for file browsing and preview features in cross-platform apps. It simplifies the process of displaying visual previews without requiring custom implementation for each file type.
