// - @react-native-async-storage/async-storage native module null in Jest
// - Hermes parser crashes when RN internals are loaded during tests

// in react-native/Libraries/NativeComponent/ViewConfigIgnore.js.
// This module uses `const T: {+[name: string]: true}` Flow syntax that the
// version of hermes-parser used by @react-native/babel-preset cannot handle.
