Setup #
Integration into a New Flutter App #
Install PSPDFKit Flutter Plugin #
-
Open
pubspec.yaml
:open pubspec.yaml
-
Add the PSPDFKit dependency in
pubspec.yaml
:dependencies: flutter: sdk: flutter + pspdfkit_flutter: any
-
Open
lib/main.dart
and replace the entire content with the contents of demo_project_main.dart.txt. This simple example will load a PDF document from local device filesystem. -
Add the PDF document you want to display in your project’s
assets
directory.-
First create a
PDFs
directory:mkdir PDFs
-
Move a sample document into the newly created
PDFs
directory, and rename it asDocument.pdf
:cp ~/Downloads/PSPDFKit.pdf PDFs/Document.pdf
-
-
Specify the
assets
directory inpubspec.yaml
:# The following section is specific to Flutter. flutter: + assets: + - PDFs/ ...
-
From the terminal app, run the following command to get all the packages:
flutter pub get
Android #
Requirements
- The latest stable version of Flutter
- The latest stable version of Android Studio
- The Android NDK
- An Android Virtual Device or a hardware device
Getting Started
-
Create a Flutter project called
pspdfkit_demo
with theflutter
CLI:flutter create --org com.example.pspdfkit_demo pspdfkit_demo
-
In the terminal app, change the location of the current working directory to your project:
cd pspdfkit_demo
-
Update the
pluginManagement
block in theandroid/settings.gradle
file as follows:pluginManagement { ... + buildscript { + repositories { + mavenCentral() + maven { + url = uri("https://storage.googleapis.com/r8-releases/raw") + } + } + dependencies { + classpath("com.android.tools:r8:8.3.37") + } + } } // Upgrade Kotlin version. plugins { id "dev.flutter.flutter-plugin-loader" version "1.0.0" id "com.android.application" version "7.3.0" apply false - id "org.jetbrains.kotlin.android" version "1.7.10" apply false + id "org.jetbrains.kotlin.android" version "1.8.22" apply false }
This step involves enabling R8 for code shrinking (not required for AGP 8.* and above) and upgrading the Kotlin version.
-
Open the app’s Gradle build file,
android/app/build.gradle
:open android/app/build.gradle
-
Modify the compile SDK version and the minimum SDK version:
android { - compileSdkVersion flutter.compileSdkVersion + compileSdkVersion 34 ... defaultConfig { - minSdkVersion flutter.minSdkVersion + minSdkVersion 21 ... } compileOptions { - sourceCompatibility JavaVersion.VERSION_1_8 - targetCompatibility JavaVersion.VERSION_1_8 + sourceCompatibility JavaVersion.VERSION_17 + targetCompatibility JavaVersion.VERSION_17 } // If you have this block, update the `jvmTarget` to 17. kotlinOptions { - jvmTarget = '1.8' + jvmTarget = '17' } ... }
-
Add the AppCompat AndroidX library to your
android/app/build.gradle
file:dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" + implementation 'androidx.appcompat:appcompat:1.4.0' }
-
Open the project’s main activity class,
android/app/src/main/kotlin/com/example/pspdfkit_demo/pspdfkit_demo/MainActivity.kt
:open android/app/src/main/kotlin/com/example/pspdfkit_demo/pspdfkit_demo/MainActivity.kt
-
Change the base
Activity
to extendFlutterAppCompatActivity
:- import io.flutter.embedding.android.FlutterActivity; + import io.flutter.embedding.android.FlutterAppCompatActivity; - public class MainActivity extends FlutterActivity { + public class MainActivity extends FlutterAppCompatActivity { }
Alternatively you can update the
AndroidManifest.xml
file to useFlutterAppCompatActivity
as the launcher activity:<activity - android:name=".MainActivity" + android:name="io.flutter.embedding.android.FlutterAppCompatActivity" android:launchMode="singleTop" android:theme="@style/LaunchTheme" android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode" android:hardwareAccelerated="true" android:windowSoftInputMode="adjustResize" android:exported="true">
NOTE:
FlutterAppCompatActivity
isn’t an official part of the Flutter SDK. It’s a customActivity
that extendsAppCompatActivity
from the AndroidX AppCompat library, and it’s necessary to use PSPDFKit for Android with Flutter. You can read more about this in the AppCompatActivity Migration guide. -
Update the theme in
android/app/src/main/res/values/styles.xml
to usePSPDFKit.Theme.default
as the parent:- <style name="NormalTheme" parent="Theme.AppCompat.Light.NoActionBar"> + <style name="NormalTheme" parent="PSPDFKit.Theme.Default">
This is to customize the theme of the PSPDFKit UI. You can read more about this in the appearance styling guide.

Requirements
Getting Started
PSPDFKit for Web library files are distributed as an archive that can be extracted manually.
-
Download the framework here. The download will start immediately and will save a
.tar.gz
archive likePSPDFKit-Web-binary-<%= latest_version(:web) %>.tar.gz
to your computer. -
Once the download is complete, extract the archive and copy the entire contents of its
dist
folder to your project’sweb/assets
folder or any other folder of your choice inside the web subfolder. -
Make sure your
assets
folder contains thepspdfkit.js
file and apspdfkit-lib

MIME typeset. Read more about this in the Troubleshooting section. -
Include the PSPDFKit library in your
index.html
file:
<script src="assets/pspdfkit.js"></script>

Run the app with:
flutter run
Example App #
To see PSPDFKit for Flutter in action check out our Flutter example app.
Showing a PDF document inside your Flutter app is as simple as this:
```dart
PspdfkitWidget(documentPath: 'file:///path/to/Documentpdf')
```
Upgrading to a Full PSPDFKit License Key #
PSPDFKit is a commercial product and requires the purchase of a license key when used in production. By default, this library will initialize in demo mode, placing a watermark on each PDF and limiting usage to 60 minutes.
To purchase a license for production use, please reach out to us via https://pspdfkit.com/sales/form/.
To initialize PSPDFKit using a license key, call either of the following before using any other PSPDFKit APIs or features:
To set the license key for both Android and iOS, use:
await Pspdfkit.setLicenseKeys("YOUR_FLUTTER_ANDROID_LICENSE_KEY_GOES_HERE", "YOUR_FLUTTER_IOS_LICENSE_KEY_GOES_HERE");
To set the license key for the currently running platform, use:
await Pspdfkit.setLicenseKey("YOUR_FLUTTER_LICENSE_KEY_GOES_HERE");
