remove_deprecations_in_breaking_versions

Remove deprecated elements in breaking versions.

The analyzer produces this diagnostic in packages that have a "breaking" version number (x.0.0 or 0.x.0) for every declaration that has a @Deprecated annotation.

Given a package with a pubspec.yaml file containing:

name: p
version: 2.0.0
environment:
  sdk: ^3.9.0

The following code produces this diagnostic because the function f is annotated with @deprecated:

@Deprecated('...')
void f() {}
​
void g() {}

If the declaration should be removed in the next release of the package, then remove the declaration:

void g() {}

If you are not making a breaking change, then use a minor or patch version increment for the package:

name: p
version: 1.0.1
environment:
  sdk: ^3.9.0
