Jest failed after upgrade to react-native 0.64

Describe the bug

Recently I upgraded my project to 0.64 version and faced this issue when I run jest. The same error happened even after I tried with a fresh react-native project with package react-navigation.

type ErrorHandler = (error: mixed, isFatal: boolean) => void;
         ^^^^^^^^^^^^

SyntaxError: Unexpected identifier

  at Runtime.createScriptFromCode (node_modules/jest-runtime/build/index.js:1350:14)
  at Object.<anonymous> (node_modules/react-native/jest/setup.js:439:6)

Expected behavior

Jest should be completed without error.

Steps to Reproduce

1. react-native init
2. install all the react-navigation packages
3. set up the testing environment as documented. (https://callstack.github.io/react-native-testing-library/docs/react-navigation#setting-up-the-test-environment)
4. run jest

Please help. Thanks in advance 🙏🏿

Check the path to the file that has unsupported syntax (type keyword), it’s the most important one. It points to a file located inside node_modues/@react-native/. So, you’ll need to add @react-native next to @react-navigation in the transformIgnorePatterns config.

Would you like to contribute a fix to the docs? 😃

transformIgnorePatterns: [
-  'node_modules/(?!(jest-)?react-native|@react-native-community|@react-navigation)',
+  'node_modules/(?!(jest-)?@?react-native|@react-native-community|@react-navigation)',
]

ahh okay, replaced with jest.mock('react-native/Libraries/Animated/NativeAnimatedHelper'); works 👍🏿
