I dont understand why this error show

[prakasa1904]

undefined is not an object (evaluating '_this._drawer.close'

I think, my code already same with your sample, :

export default class Simple extends Component { static PropTypes = { title: PropTypes.string.isRequired, setTitle: PropTypes.func.isRequired, setContent: PropTypes.func.isRequired, children: PropTypes.node.isRequired, }

state={ drawerOpen: false, drawerDisabled: false, }

closeDrawer = () => { this._drawer.close() }

openDrawer = () => { this._drawer.open() }

render() { return ( <Drawer ref={(ref) => this._drawer = ref} type='static' styles={drawerStyles} content={} onOpen={() => { this.setState({drawerOpen: true}) }} onClose={() => { this.setState({drawerOpen: false}) }} disabled={this.state.drawerDisabled} openDrawerOffset={(viewport) => { return 100 }} closedDrawerOffset={() => 50}

<ContentLayout openDrawer={this.openDrawer}

{ this.props.children } ) } }

here my depends :

"dependencies": { "@expo/vector-icons": "^4.0.0", "native-base": "^2.1.1", "react": "16.0.0-alpha.6", "react-native": "0.43.2", "react-native-gifted-listview": "0.0.15", "react-native-gridview": "^0.1.1", "react-native-loading-spinner-overlay": "^0.4.4", "react-native-menu": "^0.20.2", "react-native-rest-client": "^0.1.1", "react-native-vector-icons": "^4.0.1" },

should I changes same as example ?

done with this issues, I think we need update example ref with props only. Coz, every render ref return undefined.

just changes open with our component state and changes it with some function there.

Your code is not really readable for anyone. You can add formatting by wrapping it in ``` blocks, see https://help.github.com/articles/basic-writing-and-formatting-syntax/#quoting-code
