react-native-dialog


A pure JavaScript React-Native dialog that follows closely the UI of its native counterpart while expanding its features.

Features

- Support for iOS and Android (JavaScript API)
- A flexible declarative API
- Follows closely the UI of a native dialog/alert
- Can be used both as an alert and as an input prompt
- Can be injected with any component

Demo

Setup

Install the library using npm or yarn:

``bash

using npm

$ npm install react-native-dialog --save

using yarn

$ yarn add react-native-dialog
`

Usage

React-native-dialog exposes a set of components that can be used to build the UI of the dialog:

- Dialog.Container: This component is the root component of the dialog and all the other components should be nested inside it.
- Dialog.Title: A Text component styled as a native dialog title.
- Dialog.Description: A Text component styled as a native dialog description.
- Dialog.Button: A component styled as a native dialog button.
- Dialog.Input: A TextInput component styled as a native dialog input.
- Dialog.Switch: A native Switch component with an optional label.

1. Import react-native-dialog:

`javascript
import Dialog from "react-native-dialog";
`

2. Create a dialog and nest its content inside of it:

`javascript
render () {
return (


Account delete

Do you want to delete this account? You cannot undo this action.





)
}
`

3. Then simply show it by setting the visible prop to true:

`javascript
render () {
return (


Account delete

Do you want to delete this account? You cannot undo this action.





)
}
`

The visible prop is the only prop you'll really need to make the dialog work: you should control this prop value by saving it in your state and setting it to true or false when needed.

A complete example

The following example consists in a component (DialogTester) with a button and a dialog.
The dialog is controlled by the dialogVisible state variable and it is initially hidden, since its value is false.
Pressing the button sets dialogVisible to true, making the dialog visible.
Inside the dialog there are two button that, when pressed, sets dialogVisible to false, hiding the dialog.

`javascript
import React, { Component } from "react";
import { Text, TouchableOpacity, View } from "react-native";
import Dialog from "react-native-dialog";

export default class DialogTester extends Component {
state = {
dialogVisible: false
};

showDialog = () => {
this.setState({ dialogVisible: true });
};

handleCancel = () => {
this.setState({ dialogVisible: false });
};

handleDelete = () => {
// The user has pressed the "Delete" button, so here you can do your own logic.
// ...Your logic
this.setState({ dialogVisible: false });
};

render() {
return (


Show Dialog


Account delete

Do you want to delete this account? You cannot undo this action.





);
}
}
`

Frequently Asked Questions

$3

To achieve a look even closer to the native iOS dialog you can provide your own component in the blurComponentIOS prop of a Dialog.Container and it will be injected in the dialog to be used as a background.
The blurComponentIOS can be useful for example if you want to apply native blur effect to the dialog.
Here is an example using react-native-blur:

`javascript
render() {
const blurComponentIOS = (
style={StyleSheet.absoluteFill}
blurType="xlight"
blurAmount={50}
/>
)
return (

visible={this.state.dialogVisible}
blurComponentIOS={blurComponentIOS}
>
Account delete

Do you want to delete this account? You cannot undo this action.





);
}
`

react-native-dialog uses react-native-modal for the backdrop and any properties you add to Dialog.Container are mapped through to the modal.
react-native-modal has an onBackdropPress property that can be used to register clicks on the backdrop.

Below is an example on how you can close the dialog by tapping outside.

`javascript
render() {
const { onCancel, visible } = this.props;
const reactNativeModalProps = {
onBackdropPress: onCancel,
};
return (

{'title'}


);
}

onCancel() {
this.setState({
visible: false,
})
}
`

Acknowledgments

Thanks to the user @honaf who has kindly offered the react-native-dialog namespace.
Also thanks to the user @leecade who offered the namespace react-native-alert` (which has not been used since "Dialog" seems to suit better this component).
