Swap the arguments to `has` (#2758) Towards #2616 These were originally written with the callback argument first because it adds a slight convenience in an IDE where the fields can be autocompleted before having to type the name argument. It's more common in Dart for the callback argument to be trailing, and it reads nicer with the name argument first. Add fix data to correct use sites. Migrate `has2` call sites in `checks` and `checks_codegen` back to `has`, and keep `has2` forwarding to `has` until downstream `has2` callers are migrated.
Welcome! package:test is the standard testing library for Dart and Flutter. If you have questions about Dart testing, please see the docs for package:test. package:test_api and package:test_core are implementation details and generally not user-facing.
package:checks is a relatively new library for expressing test expectations. It's a more modern version of package:matcher and features a literate API.
