Plugin to fill/retrieve PDF fields

This plugin allows to fill fields from PDF documents and export the result in a new file. The plugin is also able to extract all the fields' content of a given PDF.

Demo

Compatibility

On Android, the plugin is using the iTextPDF v5 library and is compatible with all Android versions (API 16+).

On iOS, the plugin is using PDFKit and is thus limited to iOS 11.

Getting started

How it works

This plugin has two features :

  • Read the content of a PDF file and extract all the fields with their values
  • Fill the fields of a PDF and export the result in a new file (always in the filesystem)

Source

The Dart API allows you to pick a file from :

  • the Flutter project resources,
  • the app resources (Android/iOS),
  • or the filesystem

Android permissions

On Android, please add the following permissions to your AndroidManifest.xml:

// Only required if you want to read the content of PDF stored in the filesystem
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

// Only required if you want to create a PDF in the filesystem
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Your Flutter application

Firstly, please import the plugin:

import 'package:fillable_pdf_form/fillable_pdf_form.dart';

Then please follow the example to use the right method.
