uploadDocument method Null safety
- {required SchemaDocument doc,
- required String label}
Upload a Document
Uploads a document to IPFS. Returns the UploadDocumentResponse
if successful, and null if the document was not found.
// Define a document
final def = SchemaDefinition(label: 'MySchema', fields: {'name': 'String', 'age': 'Int'});
// Create empty document from definition
final doc = def.newDocument();
doc.set<String>('name', 'John');
doc.set<int>('age', 30);
// Upload document to IPFS
final res = await MotorFlutter.to.uploadDocument(doc);
if (res == null) {
throw Exception('Failed to upload document');
}

creator: address.value,
definition: doc.definition,
fields: doc.fields,
label: label,
));
if (res == null) {
throw UnmarshalException<UploadDocumentResponse>();
}
return res;
