Accessibility Fixes and Additions

Last year Facebook took the GAAD pledge to improve accessibility within React Native. 0.65 shares the results of this pledge and other accessibility wins! Some notable changes include:

  • Allow specification of high contrast light and dark values for iOS. See documentation for more details.
  • Added getRecommendedTimeoutMillis API on Android. This exposes a user’s preferred default timeout value as set in Android’s accessibility options and is for users who may need extra time to review or reach controls, etc.
  • General fixes to ensure TalkBack/VoiceOver properly announce UI states such as disabled and unselected on components.

You can follow along or contribute to our outstanding accessibility issues here!

Notable Dependency Version Updates and Gotchas

  • react-native-codegen version 0.0.7 is now needed as a devDependency in the package.json.
  • JCenter has been sunsetted and read-only now. We have removed JCenter as a maven repository and updated dependencies to use MavenCentral and Jitpack.
  • Upgraded OkHttp from v3 to v4.9.1. See Upgrading to OkHttp 4 for more details on changes.
  • Upgraded to Flipper 0.93 to support Xcode 12.5. See Flipper changelog here.
  • Android Gradle Plugin 7 support
  • Apple Silicon requires a linker workaround. See @mikehardy’s note about this.
