JS class

The annotation for JS interop members.

This is meant to signify that a given library, top-level external member, or inline class is a JS interop declaration.

Specifying name customizes the JavaScript name to use. This can be used in the following scenarios:

• Namespacing all the external top-level members, static members, and constructors of a library by annotating the library with a custom name.
• Namespacing all the external static members and constructors of an inline class by annotating the inline class with a custom name.
• Renaming external members by annotating the member with a custom name.

In the case where name is not specified, we default to the Dart name for inline classes and external members.

Note: package:js exports an @JS annotation as well. Unlike that annotation, this is meant for inline classes, and will result in more type-checking for external top-level members.
