WriteFilesFlow class

Multi-step write files flow for wallet integration.

Similar to WriteBlobFlow but encodes multiple files into a quilt and returns per-file patch IDs at the end.

Usage:

final flow = await directClient.writeFilesFlow(files: myFiles);

// Step 1: Encode files into quilt
await flow.encode();

// Step 2: Get register transaction → sign externally
final registerTx = await flow.register(WriteFilesFlowRegisterOptions(
  epochs: 3,
  owner: myAddress,
  deletable: true,
));
final registerResult = await wallet.signAndExecute(registerTx);

// Step 3: Upload quilt blob
await flow.upload(WriteBlobFlowUploadOptions(
  digest: registerResult.digest,
));

// Step 4: Get certify transaction → sign externally
final certifyTx = flow.certify();
await wallet.signAndExecute(certifyTx);

// Step 5: Get file results
final files = await flow.listFiles();
for (final file in files) {
  print('File ID: ${file.id}');
}
