Installation

Supported Platforms

The library is available for the following Flutter 3.44.0+ and Dart 3.12.0+ platforms:

• Android 6.0 (API 23) and newer
• iOS 13.4 and newer

How To Install

1. Prerequisites

• Flutter SDK installed (Get Started)
• A working Flutter project (flutter create my_app if starting fresh)

2. Add Dependency

Add the package from pub.dev:

flutter pub add flutter_powerauth_mobile_sdk_plugin

3. Configure Native Platforms

Android

Set the minimum SDK version to 23 and enable Java 17. New Flutter projects use Kotlin DSL in android/app/build.gradle.kts:

android {
    defaultConfig {
        minSdk = 23
    }

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }
}

For a project that still uses Groovy in android/app/build.gradle, use:

android {
    defaultConfig {
        minSdkVersion 23
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }
}

iOS

In ios/Podfile, ensure the platform version is at least 13.4 when the project uses CocoaPods:

platform :ios, '13.4'

Then install pods:

cd ios
pod install
cd ..

Flutter projects configured to use Swift Package Manager consume the plugin’s package integration automatically; do not add the native PowerAuth2 package separately.

If the application uses Face ID for biometric authentication, add a user-facing usage description to ios/Runner/Info.plist:

<key>NSFaceIDUsageDescription</key>
<string>Use Face ID to authenticate.</string>

Replace the example text with a description appropriate for your application. iOS requires this key before an application can access Face ID.

4. Initialize PowerAuth in Dart

In your main Dart file or wherever needed:

import 'package:flutter_powerauth_mobile_sdk_plugin/flutter_powerauth_mobile_sdk_plugin.dart';

final powerAuth = PowerAuth("my-instance-id");
