	Setup of React native push notification is very easy things. But documentations and all that isn't right the way it should be.

	So in this short snippet I'm going to explain, How you can achieve this without any issues!

	#This guid is for only Android Developers for now

	#First step
	> we will use this library for push notification: https://github.com/zo0r/react-native-push-notification Install this library on with your project
	> and then do a link it as mentioned. But Only linking is not enough at all!

	function checkImage(imageSrc, good, bad) {
	var img = new Image();
	img.onload = good;
	img.onerror = bad;
	img.src = imageSrc;
	}

	//now we need to run the function written above to see if the image is loaded or not via callback

	checkImage(

	# to use this function as a bash command add this to your bash_profile ~ root directory in windows and then reload bash profile
	# and you're ready to go simply type: gitPush "commit message that you want to add";;
	gitPush() {
	git add .
	#Here "$1" as the arugment that'll collect the mnessage for commit
	git commit -am "$1"
	git push -u origin master
	}


	function checkPasswordForUserName(userFullName, userPass) {
	const userNamesList = userFullName.toLowerCase().split(" ");
	const firstThreeChars = userFullName.substring(0, 3);
	const lowerCasePassword = userPass.toLowerCase();
	const isUserNameInPassword = (name) => (
	lowerCasePassword.includes(name) \|\|
	lowerCasePassword.includes(firstThreeChars)
	);


	let request

	const performAnimation = () => {
	request = requestAnimationFrame(performAnimation)
	//You can do whatever you want continously or conditional based on your needs, have fun!
	//Here your code goes for using as setTimeout simply call cancelAnimationFrame(request) or to use as setInterval don't use the cancelAnimation
	}

	requestAnimationFrame(performAnimation)

	By default in Xampp, wamp server you can't run these functions `exec` or `shell_exec` to run these shell commands you
	need to edit `php.ini` file and add/edit this command to like this `set safe_mode_exec_dir (line after = is empty, so IT IS ON!!!) set it off!`
