React Native Toast Message: An Introduction

Toast messages are brief notifications that pop up on the screen to inform the user of a successful action or to provide additional information. Toast messages are often used in mobile applications to provide feedback to the user about the outcome of their actions. React Native is a popular framework for building native mobile applications using JavaScript and React. In this article, we will explore how to create and display toast messages in React Native.

Implementing Toast Messages in React Native

React Native does not provide a built-in component for toast messages, so we will need to use third-party libraries to implement them. There are several libraries available for React Native toast messages, but we will be using the react-native-easy-toast library in this article.

To install the react-native-easy-toast library, run the following command in your terminal:

npm install react-native-easy-toast --save

Next, we will import the Toast component from the react-native-easy-toast library and render it in our component. We will also use the show method of the Toast component to display the toast message.

import React, { useState } from 'react';
import { View, Text, Button } from 'react-native';
import Toast from 'react-native-easy-toast';

const App = () => {
  const [visible, setVisible] = useState(false);

  const showToast = () => {
    setVisible(true);
  };

  const hideToast = () => {
    setVisible(false);
  };

  return (
    <View style={{flex: 1, justifyContent: 'center', alignItems: 'center'}}>
      <Button title="Show Toast" onPress={showToast} />
      <Toast
        ref="toast"
        style={{backgroundColor: 'red'}}
        position="top"
        positionValue={200}
        fadeInDuration={750}
        fadeOutDuration={1000}
        opacity={0.8}
        textStyle={{color: 'white'}}
      />
    </View>
  );
};

export default App;

In the code above, we first imported the necessary components from the React Native and react-native-easy-toast libraries. We then created a state variable, visible, to keep track of the visibility of the toast message.

Next, we created two functions, showToast and hideToast, to show and hide the toast message, respectively. The showToast function sets the visible state variable to true, while the hideToast function sets it to false.

Finally, we rendered a button in the component and passed the showToast function as the onPress prop to the button. We also rendered the Toast component and passed several props to customize its appearance and behavior.

Displaying Toast Messages

To display the toast message, we will use the show method of the Toast component and pass the message text as an argument.

const showToast = () => {
  setVisible(true);
  this.refs.toast.show('Hello, Toast!', 1000);
};

In the code above, we called
Customizing Toast Messages

One of the advantages of using the react-native-easy-toast library is the ability to customize the appearance and behavior of toast messages. The library provides several props that allow you to change the background color, text color, position, duration, opacity, and other aspects of the toast message.

Here are some of the most commonly used props for customizing toast messages:

• style: Allows you to specify the style for the toast message container. You can use this prop to change the background color, padding, and other aspects of the container.

• position: Specifies the position of the toast message on the screen. The value can be "top", "center", or "bottom".

• positionValue: Specifies the distance from the top or bottom of the screen where the toast message should be displayed.

• fadeInDuration: Specifies the duration of the fade-in animation for the toast message.

• fadeOutDuration: Specifies the duration of the fade-out animation for the toast message.

• opacity: Specifies the opacity of the toast message.

• textStyle: Allows you to specify the style for the text in the toast message. You can use this prop to change the text color, font size, and other aspects of the text.

Here is an example of customizing the appearance and behavior of the toast message:

<Toast
  ref="toast"
  style={{backgroundColor: 'red'}}
  position="top"
  positionValue={200}
  fadeInDuration={750}
  fadeOutDuration={1000}
  opacity={0.8}
  textStyle={{color: 'white'}}
/>

In the code above, we specified the background color, position, duration, opacity, and text color for the toast message.
