You can see that with the use of percentages it's much easier to create responsive applications.
Sample application will be linked soon.
Why? #
Imagine you have a phone with a big screen size (I own a OnePlus 6, quite big). You develop a flutter application using a bunch of Cards, Container and what not. Sometimes you'll find yourself giving them heights and widths, you try different heights to fit the perfect match for your phone. Great! Now try running this Flutter application on an iPhone 5s, you be bombarded with a ton of error messages and Screen Overflow warnings on your phone. This is where Flutter Screen Scaler comes into play! It will resize all your widgets according to the percentage you provide and the phone's screen dimension. It's pretty much just like using percentages in HTML.
