Portal
): stop using legacy context API in React 18Reviewers should focus on:
We assume that React 18 users of Blueprint are not using legacy APIs. The
<Portal>
component currently has support for both the new context API and the legacy one. The backwards-compatible implementation (initialized viaPortal.contextTypes = ...
) triggers a warning in React 18 strict mode which we would like to avoid (see #6572).This is a breaking change but likely a welcome one for React 18 users. Open to feedback; leave a comment below.
