pdfium 0.0.1

pub package

Flutter Pdfium #

This project aims to wrap the complete Pdfium API in dart, over FFI.

It's currently only a proof-of-concept, but can successfully produce bitmaps from PDF files.

This has the potential to build a truly cross platform, high-level API for rendering and editing PDFs on all 5 platforms.

Goals #

  • [ ] Build Pdfium shared libraries for all platforms. (pdfium_builder)
  • [ ] Find a way to generate FFI code from C headers.
  • [ ] Integrate into flutter_pdf_viewer.

Thanks #

A big THANK YOU to Google for open sourcing Pdfium, and releasing dart:ffi.

Maintenance issues and suggestions

Provide a file named CHANGELOG.md. (-20 points)

Changelog entries help developers follow the progress of your package. See the example generated by stagehand.

Support latest dependencies. (-10 points)

The version constraint in pubspec.yaml does not support the latest published versions for 1 dependency (ffi).

The package description is too short. (-16 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Maintain an example. (-10 points)

Common filename patterns include main.dart, example.dart, and pdfium.dart. Packages with multiple examples should provide example/README.md.

For more information see the pub package layout conventions.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
