Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/51779 Adds `noflow` to a bunch of Node.js script files. In the future, these files could be migrated to use `flow strict-local` or `flow strict` using comment syntax for type annotations. But for now, adding `noflow` makes it explicit that these are known to not be typechecked. Changelog: [Internal] Reviewed By: SamChou19815 Differential Revision: D75883703 fbshipit-source-id: a8fed3aaa9c55ecda919a705940f8b34504cb07c

|
* Based off of the build script from Metro, and tweaked to run in just one
|
|
* package instead of in a monorepo. Just run `build.js` and the JS files in
|
|
* `src/` will be built in `lib/`, and the original source files will be copied
|
|
* over as `Example.js.flow`, so consumers of this module can still make use of
|
|
* type checking.

* Call this script with the `--verbose` flag to show the full output of this
