You can try out the Flash Message Playground app to get a tease of the functionalities of this lib.

Basic Usage

The FlashMessage component it's build to a global use, so you have to instance this component once in your main app screen always as a last inserted component:

import React from "react";
import { View } from "react-native";
import FlashMessage from "react-native-flash-message";

export default class App extends React.Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <View ref={"otherView1"} />
        <View ref={"otherView2"} />
        <View ref={"otherView3"} />
        {/* GLOBAL FLASH MESSAGE COMPONENT INSTANCE */}
        <FlashMessage position="top" /> {/* <--- here as last component */}
      </View>
    );
  }
}

After that you only need to call showMessage or hideMessage methods from anywhere in your app.

If you don't need a global use for (e.g. will use only in one screen) you can instance your FlashMessage Component with a ref ID (or other capture ref method):

<View style={{ flex: 1 }}>
  <YourMainApp />
  <FlashMessage ref="myLocalFlashMessage" />   {/* <--- here as last component always with `ref` */}
<View>

Show some message

Now that you already instantiated the global FlashMessage component, when you need to show some message in your app you could use the showMessage method in any screen or view. This is a global method that receive a message object with your message detail:

import React from "react";
import { View, Button } from "react-native";

import { showMessage, hideMessage } from "react-native-flash-message";

class MyScreen extends React.Component {
  render() {
    return (
      <View style={{ flex: 1 }}>
        <Button
          onPress={() => {
            /* HERE WE GONE SHOW OUR FIRST MESSAGE */
            showMessage({
              message: "Simple message",
              type: "info",
            });
          }}
          title="Request Details"
          color="#841584"
        />
      </View>
    );
  }
}

The message object obligatorily requires some message attribute. If you need to show a message with two lines (title and more details) you could use message attr for title and description attr for details line:

showMessage({
  message: "Hello World",
  description: "This is our second message",
  type: "success",
});

The type attribute set the type and color of your flash message, default options are "success" (green), "warning" (orange), "danger" (red), "info" (blue) and "default" (gray).

By default all of the messages will be displayed with transitions and with autoHide after 1850 ms enabled. If you need to programmatically hide some message, you can call hideMessage() .

Other message object attributes will be detailed below.

Props

Message Object

When you call showMessage method you need pass a message object to show your message. In this call you could pass some custom attributes to customize your message. Most of the FlashMessage Component props can be passed in runtime calls of showMessage. This common props/attributes are identified in Props table as In Message Object.

If you need to customize de background color or text color of your message beyond the default types (success, warning, info and danger) you could use the backgroundColor or/and color attributes in your message object:

showMessage({
  message: "My message title",
  description: "My message description",
  type: "default",
  backgroundColor: "purple", // background color
  color: "#606060", // text color
});

If you need to handle the press/touch event in your message, you could use the onPress attribute to take some action:

showMessage({
  message: "My message title",
  description: "My message description",
  type: "success",
  onPress: () => {
    /* THIS FUNC/CB WILL BE CALLED AFTER MESSAGE PRESS */
  },
});
