checkData function

void checkData({ required dynamic data, required BuildContext context, required String successMsg, required String errorMsg, required BehaviorSubject<bool> listener, required bool listenerValue, required bool popContext, required Function? successCallback, })

checkData checks the validity of the data returned from the api and proceeds if successful or shows an error message if there are any errors

variables passed in are custom

data - the data to be checked against context - the context successMsg - the message to be displayed on successful completion errorMsg - the message to be displayed in case of any error listeners - the listener to be updated listenerValue - the value to update the listener with

Implementation

    listener.add(listenerValue);

    /// Close drawer
