The declaration named 'main' must be a function.

              Description

              #

              The analyzer produces this diagnostic when a library contains a declaration
              of the name `main` that isn't the declaration of a top-level function.

              Example

              #

              The following code produces this diagnostic because the name `main` is
              being used to declare a top-level variable:

                dart

var main = 3;

                content_copy

              Common fixes

              #

Use a different name for the declaration:

                dart

var mainIndex = 3;

                content_copy
