Open & view a document in Flutter

This guide will help you to view a document using the PDFTron Flutter SDK for Android.


Replace lib/main.dart with what is shown here:

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:pdftron_flutter/pdftron_flutter.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  String _version = 'Unknown';

  void initState() {


  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String version;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      PdftronFlutter.initialize("Insert commercial license key here after purchase");
      version = await PdftronFlutter.version;
    } on PlatformException {
      version = 'Failed to get platform version.';

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _version = version;

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('PDFTron flutter app'),
        body: Center(
          child: Text('Running on: $_version\n'),
