C2pa class

Main entry point for the c2pa_flutter plugin.

Provides factory methods for creating reader and writer instances.

Call init once before using any other C2PA functionality:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await C2pa.init();
  runApp(MyApp());
}

Then use the reader and writer:

// Read
final reader = C2pa.reader();
final store = reader.readFromFile('/path/to/image.jpg');
final manifest = store?.active;

// Write
final writer = C2pa.writer();
final signedBytes = await writer.sign(
  imageBytes: originalBytes,
  mimeType: 'image/jpeg',
  manifest: manifest,
  signer: signer,
);
