data_table_2 package not found when download code using DataTable

Hi,

I was trying to use the DataTable but for some reason it was generating an error and asked to download the source code.
But after I downloaded the source code and opening in VSCode it complained about missing package package:data_table_2/data_table_2.dart, which was not found.

Did I miss something?

BTW, I just gave up using DataTables and used ListView instead.

Best Regards,
Sandro
