i am getting this error when i am trying to extract a function form the smart contract code example : contract.function("getTicketNumber").

dart points to this line which cause that error

@khaledmurtaja Please upload your smart contract, your generated file (if you have them), and your code that is calling the function. Thanks!

Additionally, please upload the error. If you do not have an exact trace on it; wrap your code in try...catch and have the catch response by (err, trace) and print both out to the console
