Exception is thrown during Jest test when using Paper components.

[rafabulsing]

Current behaviour

Using the library's components results in exception being thrown when running tests with Jest.

C:\ReactNativePaperJestTest\node_modules\react-test-renderer\cjs\react-test-renderer.development.js:2611
      throw error;
      ^

Node.js v20.12.0

Expected behaviour

The test should run with no exceptions.

How to reproduce?

1. Create new app with npx react-native@latest init ReactNativePaperJestTest
2. Go through the library's setup, as per the docs
3. Add the PaperProvider component to the app
4. Run the tests with npm test

Alternatively, check out this GitHub repo.

What have you tried so far?

Adding the following to jest.config.js:

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

causes the error to change a bit:

C:\ReactNativePaperJestTest\node_modules\flow-parser\flow_parser.js:818
throw a}function
