CalljmpDevice class abstract

Abstract platform interface for device attestation and integrity verification.

This class defines the contract that platform-specific implementations must follow to provide device attestation capabilities. It supports both iOS App Attestation and Android Play Integrity verification.

Platform Interface Pattern

This follows Flutter's platform interface pattern where:

• Abstract interface defines the contract
• Platform-specific implementations provide actual functionality
• Default implementation uses method channels for native communication

Supported Operations

• iOS App Attestation: Generate keys and create attestations using Secure Enclave
• Android Play Integrity: Request integrity tokens for app verification

Example Usage

// Use the default instance
final device = CalljmpDevice.instance;

// iOS: Generate attestation key
final keyId = await device.appleGenerateAttestationKey();

// iOS: Create attestation
final attestation = await device.appleAttestKey(keyId, challengeData);

// Android: Request integrity token
final integrity = await device.androidRequestIntegrityToken(
  projectNumber,
  challengeData,
);

Custom Implementation

To provide a custom implementation:

class CustomCalljmpDevice extends CalljmpDevice {
  @override
  Future<String> appleGenerateAttestationKey() async {
    // Custom implementation
  }
  // ... implement other methods
}

// Register the custom implementation
CalljmpDevice.instance = CustomCalljmpDevice();
