Abstract classes in Dart are like blueprints for creating other classes. They provide a basic structure and some methods, but not all of them.🏗️
Sometimes, abstract classes include methods that are just declared (with no actual code inside). These are called abstract methods.📝
( Think of it like having a recipe card with some steps missing. It tells you what the recipe should be, but not exactly how to make it. 🍽️ )
Because abstract classes have these missing parts (abstract methods), they're considered incomplete on their own. ❌
( It's like having a puzzle with missing pieces. You can see the overall picture, but it's not complete until you fill in the missing parts. 🧩 )
Since abstract classes are incomplete, they lack the necessary functionality to be useful by themselves. 🚫
( It's like trying to use a recipe card with missing steps to cook a meal. Without all the instructions, you can't make the dish properly. 🍳 )
In simple terms, you can't create instances of abstract classes in Dart because they're like incomplete recipes. They provide a basic outline, but you need to fill in the missing parts before they become useful. Instead, you use them as templates for creating complete classes that have all the necessary functionality. 🛠️
