React Redux - undefined is not an object evaluating this.props.navigation.navigate


I am new to Redux and I don't understand what is wrong with the following set up. I got error: TypeError: TypeError: undefined is not an object (evaluating 'this.props.navigation.navigate')

For actions, I have a function for login:

export const loginWithEmail = ({email, password}) => async (dispatch) => {
    dispatch({type: "LOADING"})
    try {
        let user = await auth.signInWithEmailAndPassword(email, password);
        dispatch({type: "LOGIN_SUCCESS", payload: user})
    } catch (error) {
        dispatch({type: "LOGIN_FAILURE"})
    }
}

Login component:

class Login extends Component {
  componentWillReceiveProps(nextProps) {
    if(!_.isEmpty(nextProps.user)) {
      this.props.navigation.navigate('Home');
    }
  }

  login() {
    const {email, password} = this.props;
    this.props.loginWithEmail({email, password});
  }

  render() {
    return (
      ...
    )
  }
}

const mapStateToProps = state => {
  return {
    email: state.auth.email,
    password: state.auth.password,
    error: state.auth.error,
    user: state.auth.user
  }
}

export default connect(mapStateToProps, {loginWithEmail})(Login);

In my App.js

const AuthStack = createStackNavigator({
  Login: { screen: Login }
});

const MainStack = createStackNavigator(
  {
    Home: { screen: 'Home' },
    Auth: AuthStack
  },
  {
    initialRouteName: 'Home'
  }
);

const AppContainer = createAppContainer(MainStack);

export default class App extends React.Component {
  constructor(props) {
    super(props);
  }

  render() {
    const store = createStore(reducers, {}, applyMiddleware(ReduxThunk));
    return (
      <Provider store={store}>
        <AppContainer/>
      </Provider>
    );
  }
}

I did also try to use the Login component in another component like this:

const store = createStore(reducers, {}, applyMiddleware(ReduxThunk));
return (
...
    <Provider store={store}>
        <Login navigation={this.props.navigation}/>
    </Provider>

My react-navigation version is 3.2.1

Update: tried following the solution from React Native: TypeError: undefined is not an object (evaluating 'this.props.navigation.navigate') but no success


Solution

  • It's because of the other file where you are using Login screen component directly.

    <Provider store={store}>
        <Login/>
    </Provider>
    

    This will not if you are expecting this.props.navigation to have a value. The solution here would be to remove this other use of Provider.

    The following that you have already is enough to connect to Redux.

    <Provider store={store}>
        <AppContainer/>
    </Provider>
