Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/49020 ## Motivation Modernising the RN codebase to allow for modern Flow tooling to process it. ## This diff - Migrates the `Libraries/EventEmitter/*.js` and `Libraries/Image/*.js` files to use the `export` syntax. - Updates deep-imports of these files to use `.default` - Updates the current iteration of API snapshots (intended). Changelog: [General][Breaking] - Deep imports to modules inside `Libraries/EventEmitter` and `Libraries/Image/*.js` with `require` syntax need to be appended with '.default'.

|
|
* available on the native side, for example in Xcode Asset Catalogs or
|
|
* Android's drawable folder.
|
|
*
|
|
* However, keep in mind that React Native Packager does not guarantee that the
|
|
* image exists. If the image is missing you'll get an empty box. When adding
|
|
* new images your app needs to be recompiled.
|
|
*
|
|
* Prefer Static Image Resources system which provides more guarantees,
|
|
* automates measurements and allows adding new images without rebuilding the
|
|
* native app. For more details visit:
