SDK Integration

PowerAuth Flutter SDK Dependency

The PowerAuth Flutter SDK is a required dependency that will be automatically installed (if not already specified in your project).

Supported Platforms

The library is available for the following Flutter 3.44.0+ 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

Open pubspec.yaml and add:

dependencies:
  # Replace VERSION_DEFINITION with the actual package version.
  mtoken_sdk_flutter: VERSION_DEFINITION

Then run:

flutter pub get

3. Configure Native Platforms

Android

In android/app/build.gradle, make sure to set the minimum SDK version:

compileSdkVersion 37
minSdkVersion 23

Also, make sure to enable Java 17:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_17
    targetCompatibility JavaVersion.VERSION_17
}

iOS

The SDK supports both Swift Package Manager and CocoaPods. Swift Package Manager is recommended for new projects. Ensure its support is enabled in Flutter:

flutter config --enable-swift-package-manager

Set the Runner target’s minimum deployment version to iOS 13.4 or newer in Xcode. Resolve the Dart dependencies, then build the app; Flutter and Xcode resolve the Swift packages during the iOS build:

flutter pub get
flutter build ios

No CocoaPods installation or Podfile is required when Swift Package Manager is enabled.

Existing CocoaPods-based applications remain supported. When Swift Package Manager is disabled, Flutter uses the PowerAuth plugin’s podspec and resolves its native PowerAuth2 dependency through CocoaPods.

4. Import in your Dart files

import 'package:mtoken_sdk_flutter/mtoken_sdk_flutter.dart';
import 'package:flutter_powerauth_mobile_sdk_plugin/flutter_powerauth_mobile_sdk_plugin.dart';

Future<void> createMtokenInstance() async {
  final powerAuth = PowerAuth("my-instance");
  // note that an activated PowerAuth instance is required. How to activate the PowerAuth instance, follow https://github.com/wultra/flutter-powerauth-mobile-sdk documentation.

  // Then, use PowerAuth's helper function to create the mtoken instance:
  final mtoken = await powerAuth.createMobileToken();
}
