An alert to notify users about an error or something else. It can be dismissed by press, cancel, automatic, pan gesture or programmatic. It can be customized and/or you can build your own alert (BYOA) - see DropdownAlertProps on what's available.

Installation

• yarn add react-native-dropdownalert
• npm i react-native-dropdownalert --save

Usage

import the library

import DropdownAlert, {
  DropdownAlertData,
  DropdownAlertType,
} from 'react-native-dropdownalert';

create an alert promise function variable

let alert = (_data: DropdownAlertData) => new Promise<DropdownAlertData>(res => res);

add the component as the last component in the document tree so it overlaps other UI components and set alert prop with alert function

<DropdownAlert alert={func => (alert = func)} />

invoke alert

const alertData = await alert({
  type: DropdownAlertType.Error,
  title: 'Error',
  message: 'Something went wrong.',
});

Support

react minium version	react-native minium version	package version	reason
v16.8.0	v0.61.0	v5.0.0	use react hooks
v16.0.0	v0.50.0	v3.2.0	use SafeAreaView
v16.0.0-alpha.6	v0.44.0	v2.12.0	use ViewPropTypes

Using children prop

Option 1 pass child component(s) like so:

<DropdownAlert>{/* insert child component(s) */}</DropdownAlert>

Option 2 pass child component(s) like so:

<DropdownAlert children={/* insert child component(s) */} />

Either way DropdownAlert will render these instead of the pre-defined child components when alert is invoked. Check out the iOS and Android notifications in example project.

Caveats

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