PDF Document Processing Using Syncfusion Flutter PDF Library
Create, edit, and save PDF documents (.pdf) using the Syncfusion Flutter PDF library. This skill supports generating Dart code snippets for Flutter projects targeting mobile, web, and desktop platforms.
Generate Dart Code for the User's Flutter Project (default)
Trigger keywords: "show me how", "how to", "how can I", "how do I", "provide code", "provide an example", "give an example", "demonstrate", "code snippet", "sample code", "example", "sample", "give me", "show me", "main.dart", "example code", "generate code for", "codesnippet".
Workflow:
Step 1 — Detect the Platform and Suggest the Correct Package
- Inspect the workspace project files (
pubspec.yaml,main.dart, etc.) to identify the Flutter platform target (mobile, web, desktop). - Tell the user to add
syncfusion_flutter_pdfto theirpubspec.yamlbefore generating any code.
Step 2 — Generate Code from Reference Files Only
Do NOT invent, guess, or suggest any API, class, method, or property not explicitly present in the reference files.
- Read the relevant
references/*.mdfile(s) for the requested feature - Build Dart code strictly from the APIs and snippets found in those files
- Use the correct save/launch pattern for the target platform:
- Mobile →
getApplicationSupportDirectory()+OpenFile.open() - Desktop →
getApplicationSupportDirectory()+OpenFile.open() - Web → base64 + JavaScript download or
webpackage approach
- Mobile →
- Do not create or run any standalone Dart script

Rules
- Output files go in
./output/directory - Temp
.dartscripts must be created inside{skill-root}/flutter/pdf/scripts/— never in the workspace root or customerscripts/folder - Never leave temp
.dartfiles after execution - Always call
document.dispose()after saving - All units in PDF are in points (not pixels)
- Use
PdfLayoutResultto chain elements and avoid content overlap
Prerequisites
- Flutter SDK installed
- Add to
pubspec.yaml:dependencies: syncfusion_flutter_pdf: ^33.1.44 - Use the latest compatible package version from pub.dev or Syncfusion documentation.
- Run:
flutter pub get - Import in Dart code:
import 'package:syncfusion_flutter_pdf/pdf.dart';
