Toolkit
Fill & Sign is a Flutter application that explores a straightforward way to add handwritten signatures to PDF documents through a mobile-friendly workflow.
The project focuses on the essential steps of signing a document: opening a PDF, creating a signature, placing it on the required pages, and saving the updated file.
Flexible signature placement
Users can create a signature and save it as an image, then place it on individual PDF pages as needed. The application also supports multiple signatures within the same document, making it possible to handle documents that require signatures in different locations.
Save and share documents
Once the signature placements are complete, users can save the signed PDF and share the resulting file. This keeps the core document workflow in one application, from signature placement to the final output.
A focused Flutter project
Built with Flutter and Dart, Fill & Sign demonstrates a practical approach to PDF interaction and document handling in a mobile application. Its scope centers on the core signing experience rather than a full digital-signature management platform.
