Universal File Picker Widget is a premium, all-in-one file selection widget for FlutterFlow/Flutter that lets users pick any file type from their device — documents, PDFs, spreadsheets, audio, archives, APKs, and more 📁✅. It opens a modern bottom-sheet picker with optional multi-select and a clean “Select” flow, making file attachments fast, familiar, and mobile-friendly.
