_react.default.memo is not a function

[jualexandre]

I initiated a new project React Native Expo with expo init MyProject.

My dependencies:

"dependencies": {
    "@expo/vector-icons": "latest",
    "emoji-utils": "latest",
    "expo": "^32.0.0",
    "moment": "^2.24.0",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-32.0.0.tar.gz",
    "react-native-gifted-chat": "^0.7.3",
    "react-native-keyboard-spacer": "^0.4.1",
    "react-native-nav": "^2.0.2",
    "react-navigation": "^3.7.1",
    "react-redux": "^7.0.2",
    "redux": "^4.0.1",
    "redux-thunk": "^2.3.0"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0"
  },

When I make export default connect(mapStateToProps)(Chat) on my component I've the error _react.default.memo is not a function.
On the other hand, if I pass the version of react-redux to 6.0.0 I do not have this error anymore...

Ah... that said, React-Redux v7 requires a minimum React version of 16.8.4. Please upgrade your React Native and React versions accordingly.

@jualexandre I had the same issue.

Didn't realize that React Native v0.59.8 depends on React 16.5.0.

It seems that from react-redux v7 React version 16.8.4 or higher is needed, because it internally uses React.memo().
