Could you build this?
Partial Building a basic document viewer in Flutter is feasible, but writing an ultra-compact native PDF editing engine that manipulates PDF object graphs and performs page-level alterations without third-party bloat requires low-level PDF specification knowledge.
What it would actually take: Architecture requires Flutter bindings over custom C/C++ or Rust libraries interfacing with OS rendering engines (or lightweight forks like PDFium/mupdf). The hard part is implementing direct low-level PDF stream editing, font subsetting, and form-field manipulation without bloating the binary with Electron or oversized runtimes.
