roundToNearestTens
Assuming that the Snake moves one step length at a time, this method is a mathematical utility that is used to round off the passed integer argument to the nearest step value.

getRandomPositionWithinRange
This method generates a random position on the screen within the bounds of the play area. You’ll use this function to spawn a new snake when a new game starts and to render a new food for the snake an a random location everytime the Snake eats the food.

showGameOverDialog
showGameOverDialog displays a styled dialog pop-up widget when the Snake collides with any of the boundaries of the play area. This dialog displays

getRandomDirection
getRandomDirection randomly returns one of the four directions: up, down, left or right. You primarily use this function to move the Snake in a random direction when it spawns. It also optionally takes an argument that specifies whether you want the random direction it returns to be horizontal or vertical.

getPlayAreaBorder
This is method that draws a border along the edge of the screen to represent the play area where the Snake moves. If the Snake collides with this boundary, the game is over.
