Installation

Add this package to your pubspec.yaml:

dependencies:
  flutter_saafe_sdk: ^0.1.0

Or install it directly from the command line:

flutter pub add flutter_saafe_sdk

Platform Specific Setup

Android

Ensure your minSdkVersion is at least 19 (Android 4.4) and compileSdkVersion is at least 33 in your android/app/build.gradle:

android {
    compileSdkVersion 33
    defaultConfig {
        minSdkVersion 19
    }
}

iOS

Add the following to your ios/Runner/Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

Getting Started

Initialize the SDK in your app's main function:

import 'package:flutter_saafe_sdk/flutter_saafe_sdk.dart';

void main() {
  // Initialize SAAFE SDK
  SaafeSdk.initialize();
  
  runApp(const MyApp());
}

Then use the SDK to trigger the authentication flow:

void startSaafeFlow() {
  final options = SaafeRedirectOptions(
    fi: 'your_fi_token',
    reqdate: 'your_reqdate',
    ecreq: 'your_encrypted_request',
    onComplete: (data) {
      print('Flow completed: $data');
    },
    onError: (error) {
      print('Error: $error');
    },
    onCancel: () {
      print('Flow cancelled by user');
    },
  );

  final redirectInstance = SaafeSdk.triggerRedirect(context, options);
  
  // You can store the instance to close the flow programmatically later
  // redirectInstance.close(); // This will show a confirmation dialog before closing
}

UI Features

The SDK provides a modern user experience with:

• Beautiful bottom sheet modal with rounded corners
• Proper handling of keyboard presentation
• Custom close confirmation dialog with modern design
• Drag handle at the top for intuitive user interaction
• Absolute positioned close button for easy dismissal
• Loading indicators while content is loading
