"object reference not set to an instance of an object error"

Question

When I call an Api in flutter, body shows a message as follows: "object reference not set to an instance of an object". But when I check it in fiddler, it shows the data. Does anyone know why?

Answer 1

Object Reference related errors are run time errors not compiler errors. These errors normally come when you try to refer to a data item/variable which is null (Null Reference exception) or else if you are trying to refer to a variable which is not yet initialized
