LayoutIfneeded() vs SetNeedsLayout

layoutIfNeeded():

• Think of it like telling your app, “Stop everything and make sure the layout of the stuff on the screen is exactly how it should be right now.”
• It’s used when you need to see the results of any changes you’ve made to how things are arranged on the screen immediately.
• Example: Imagine you moved a picture on your screen, and you want to know where it is now; you use layoutIfNeeded().

setNeedsLayout():

• This is like telling your app, “Hey, we need to fix how things look, but it’s not urgent. Do it when you have time.”
• It’s used when you want to change how things are arranged, but you’re okay with it happening a bit later.
• Example: If you’re changing the layout of a game level and don’t need it to change right away, you use setNeedsLayout() to say, "Do it when you're not too busy."
