facebook/flow v0.151.0

on GitHub

New Features:

• Add Smart Select IDE feature. This allows you to expand or shrink your selection based on the surrounding code. For example you might expand from an identifier to the containing expression, to the whole statement. In vscode, you can do this via ctrl+shift+cmd+(left or right arrow).
• Add Enum getName(value: TEnum): string method. Given a value of the enum type, this returns the string representation of the name of the member. You will also need to update to the latest flow-enums-runtime package.

Notable bug fixes:

• Update annotate-exports codemod to add lowercase react instead of React (thanks @meandmax!).

Misc:

• Improve developer setup on Windows by exposing internal setup scripts and updating the Windows setup README.md.
• Enable cache_live_errors_artifacts and cache_signature_help_artifacts config options by default.
• Improve performance and reliability of Watchman integration.
• Error for use of super outside of class methods added in 0.148.0 has been removed.

Library Definitions:

• Update React types for React 18 release.
• Update the Map, WeakMap, Set and WeakSet constructors' iterable param to be optional as per the ECMAScript spec.
• Add typing for PageTransitionEvent as per the HTML spec (thanks @bripkens!).
• Added support for stepUp and stepDown in HTMLInputElement declaration as per the HTML spec.
