import SnackBar from 'react-native-snackbar-component'

<SnackBar visible={true} textMessage="Hello There!" actionHandler={()=>{console.log("snackbar button clicked!")}} actionText="let's go"/>

Prop	Type	Effect	Default Value
visible	boolean	Show or hide the snackbar	none
textMessage	string / function	The main message text, can also supply a function returning JSX to render custom message UI	none
actionHandler	function	Function to be called when button is pressed, if absent no action button is shown	none
actionText	message	The text of action button, will be uppercased automatically	none
backgroundColor	color	The background color of snackbar	#484848
accentColor	color	The color of action button text	orange
messageColor	color	The color of main message text	#FFFFFF
distanceCallback	function	Function to be caled whenever snackbar moves in and out or changes layout, the function will be supplied a number indicating distance taken up by snackbar on bottom or top, based on position.	(distance) => {}
position	string	The position of the snackbar: top, bottom	bottom
top / bottom / left / right	number	Use these to position the snackbar	0
autoHidingTime	number	How many milliseconds the snackbar will be hidden	0 (Do not hide automatically)
containerStyle	object	Override or add style to the root container View	{}
messageStyle	object	Override or add style to the message Text	{}
actionStyle	object	Override or add style to the action button Text	{}

When visible prop is changed, the snackbar will be animated in/out of screen
The snackbar will not auto-dismiss by itself, for auto-dismiss use setTimeout() and change value passed to prop to false,
OR you can set autoHidingTime to any particular value to hide the snackbar itself, although you will need to reset visible to false manually after the autoHidingTime period is over, since visible is controlled from outside.
This works great together with react-native-fab. See demo for example and instructions how to.
