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?

CodePudding user response：

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
