I have a simple two screens app with redux and React-Native-Navigation V2. I try to pass an item from a list to another view as a prop. Unfortunately, I get an error:
TypeError: Cannot read property 'id' of undefined
The item is passed but not received as a prop in the second view. Everything works fine when working without Redux. Am I registering the views correctly?
Views registration:
export default (store) => {
Navigation.registerComponent('example.app.FirstScreen', reduxStoreWrapper(FirstScreen, store));
Navigation.registerComponent('example.app.SecondScreen', reduxStoreWrapper(SecondScreen, store));
}
function reduxStoreWrapper (MyComponent, store) {
return () => {
return class StoreWrapper extends React.Component {
render () {
return (
<Provider store={store}>
<MyComponent />
</Provider>
);
}
};
};
}
First View:
class FirstScreen extends Component {
componentDidMount() {
this.props.listItems();
}
onItemPress = (item: Item) => {
Navigation.push(item._id, {
component: {
name: 'example.app.SecondScreen',
passProps: {
item: item
}
}
});
};
render() {
return (
<View>
<ItemsList items={this.props.items} onItemPress={this.onItemPress}/>
</View>
);
}
}
const mapStateToProps = state => {
let items = state.itemsReducer.items.map(item => ({ key: item.id, ...item }));
return {
items: items
};
};
const mapDispatchToProps = {
listItems
};
export default connect(mapStateToProps, mapDispatchToProps)(FirstScreen);
Second View:
class SecondScreen extends Component {
static propTypes = {
item: PropTypes.object.isRequired,
};
componentDidMount() {
const { item } = this.props;
this.props.listSubitems(item.id);
}
render() {
const { subitems } = this.props;
return (
<View>
<SubitemsList subitems={subitems}/>
</View>
);
}
}
const mapStateToProps = state => {
let subitems = state.subitemsReducer.subitems.map(subitem => ({ key: subitem.id, ...subitem }));
return {
subitems: subitems
};
};
const mapDispatchToProps = {
listSubitems
};
export default connect(mapStateToProps, mapDispatchToProps)(SecondScreen);
Views should be registered this way:
export default (store, Provider) => {
Navigation.registerComponentWithRedux('example.app.FirstScreen', () => FirstScreen, Provider, store);
Navigation.registerComponentWithRedux('example.app.SecondScreen', () => SecondScreen, Provider, store);
}
