Usage

import DropdownAlert from 'react-native-dropdownalert';
export default class App extends Component {
  componentDidMount() {
    this._fetchData();
  }
  _fetchData = async () => {
    try {
      // alertWithType parameters: type, title, message, payload, interval.
      // payload object that includes a source property overrides the image source prop. (optional: object)
      // interval takes precedence over the closeInterval prop. (optional: number)
      this.dropDownAlertRef.alertWithType('info', 'Info', 'Start fetch data.');
      await fetch('https://httpbin.org/get');
      this.dropDownAlertRef.alertWithType('success', 'Success', 'Finish fetch data');
    } catch (error) {
      this.dropDownAlertRef.alertWithType('error', 'Error', error);
    }
  };
  render() {
    // DropdownAlert must be last component in the document tree.
    // This ensures that it overlaps other UI components.
    return (
      <View>
        <DropdownAlert ref={ref => this.dropDownAlertRef = ref} />
      </View>
    );
  }
}

Caveats

• Modals can overlap DropdownAlert if it is not inside the modal's document tree.
• It is important you place the DropdownAlert ABOVE the StackNavigator.
