Usage

import DropdownAlert from 'react-native-dropdownalert';
export default class App extends Component {
  componentDidMount() {
    this._fetchData();
  }
  _fetchData = async () => {
    try {
      await fetch('https://mywebsite.com/endpoint/');
      // alertWithType parameters: type, title, message, payload, interval.
      // There are 4 pre-defined types: info, warn, success, error.
      // payload object with source property overrides image source prop. (optional)
      // interval overrides closeInterval prop. (optional)
      this.dropDownAlertRef.alertWithType('success', 'Success', 'Fetch data is complete.');
    } catch (error) {
      this.dropDownAlertRef.alertWithType('error', 'Error', error.message);
    }
  };
  render() {
    // Make sure DropdownAlert is the last component in the document tree.
    return (
      <View>
        <DropdownAlert ref={ref => this.dropDownAlertRef = ref} />
      </View>
    );
  }
}

Caveats

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