Hi,
First, thank you for the missions. I think it is a great way to learn Backendless functionality. I completed the serverless 101 mission using Javascript SDK, but my original intention was to do it using the Flutter SDK. To make it work with the Flutter SDK, I had to change the generated SDK method as:
Future addItem(String cartName, Map item) {
return Backendless.customService
.invoke(_serviceName, "addItem", [cartName, item]);
}
The generated code’s signature is:
Future addItem(String cartName, Object item)
