I’m Calling An API and getting response in Variable Data ($data). When data is coming then there is no Error but when I’m getting null as response then getting this error Unhandled Exception: NoSuchMethodError: The getter ‘isEmpty’ was called on null.

When I am using the below code then it is throwing me an error:

Solution

That is because $data returns null, So I’ve Used

if(data?.isEmpty ?? true)

? prevents an error if the previous part of the expression results in null and ?? true results in true if the previous part of the expression is null and therefore treats == null and isEmpty the same for the if(...) check.

Now My Code is working Fine.

Thanks for reading.

Keep Coding.
