react-native-paper-message-context

Uses react-native-paper to show messages (in form of dialog or snack) in an easy n fast form. (includes predefined styles and configuration)

Dependencies

This module needs to have instaled

• react
• react-native
• react-native-paper

react-native-paper

This module uses components from react-native-paper, so if you found a visual bug (like a snackbar that shows on top of the screen) instead of a possible message-context bug (like a dialog not showing the correct color), but that issue also in react-native-paper.

Instalation

Just run in your console

npm i react-native-paper-message-context

Usage - Principal

To use first import the MessageProvider inside your PaperProvider. If you want to handle dinamic DarkTheme I recommend you to install react-native-paper-navigation-theme-context.

import React from 'react'
import {Provider as PaperProvider} from 'react-native-paper'
import {MessageProvider} from 'react-native-paper-message-context'

// This is suposed to be your app
import Screen from './Screen'

const App = () => {
    return (
        <PaperProvider>
            <MessageProvider>
                <Screen/>
            </MessageProvider>
        </PaperProvider>
    )
}

export default App

Once made this, use the hook useMessage() to show a message.

// ...
import {useMessage} from 'react-native-paper-message-context'

const CustomComponent = () => {
    const {showMessage} = useMessage()
    return (
        <Button onPress={()=>showMessage('Hello World')}>Show Message</Button>
    )
}

export default CustomComponent

Usage - Change the message options

You can customize a little your messages with the optional parameter options:

• large: The snack for default has a short duration, with large in true, it will have a larger duration (snack) (default is false).
• static: When using dialog, if you click outside, it will be dissmissed, but if static is true, this will not happen (dialog) (default is false).
• color: The background color of the dialog or the snack, can recieve a color in format #RGB or #RRGGBB or some of the next predefined colors: 'success', 'error', 'warning' or 'info' (snack and dialog) (default is undefined, uses the PaperProvider primary color). In versions 1.2.0+ it can also CSS color names like 'red', 'hotpink' or 'gold'.
• label: The text of the button of the snack of dialog (snack and dialog) (default is 'OK').

Usage - Snack or Dialog?

Maybe you're confused because I said that the options are for a Snack or Dialog, let me explain. For default showMessage() shows a Dialog, but you can change this using useSnackForMessages and useDialogForMessages.

// ...
import {MessageProvider, useMessage} from 'react-native-paper-message-context'

const WithSnack = ({children}) => {
    const {useSnackForMessages} = useMessage()
    
    useSnackForMessages()

    return (
        <>
            {children}
        </>
    )
}

// Now any showMessage() call inside <WithSnack> will be a Snack instead of a Dialog

const App = () => {
    return (
        <PaperProvider>
            <MessageProvider>
                <WithSnack>
                    <Screen>
                </WithSnack>
            </MessageProvider>
        </PaperProvider>
    )
}

Another option if you don't want to make all of this, useMessage() provides also two functions to show specificaly a Dialog or a Snack: showSnack() and showDialog().

// ...

const CustomComponent = () => {
    const {showSnack, showDialog} = useMessage()

    return (
        <View>
            <Button onPress={()=>showSnack('Nice',{color:'success'})}>
                Show a Snack saying something went fine
            </Button>
            <Button onPress={()=>showDialog('Error',{color:'danger'})}>
                Show a Dialog saying something went very wrong
            </Button>
        </View>
    )
}

export default CustomComponent

Usage - Ask Dialog

In version 1.1.0+, there's a new dialog used to make actions if the yes button is pressed, its called Ask.

// ...

const CustomComponent = () => {
    const {ask, showMessage} = useMessage()

    const hackNASA = () => {
        showMessage('NASA Hacked',{color:'success'})
    }

    const askToLog = () => {
        ask('Are you sure you wanna hack the NASA?',hackNASA,undefined,{
            color:'warning',
            label:['NEVER','YES PLEASE']
        })
    }

    return (
        <View>
            <Button onPress={askToLog}>start hack</Button>
        </View>
    )
}

export default CustomComponent
