Difference Between final and const Keywords in Dart | Dart Tutorial for Flutter in Hindi | #13

The final and const keywords are similar in that they are used to declare variables whose value cannot be changed after they are initialized. However, there are some key differences between the two keywords:
final: The final keyword is used to declare a variable whose value cannot be changed after it is initialized. The value of a final variable is determined at runtime. This means that the value of a final variable can be different for different objects, but once it is set, it cannot be changed.
const: The const keyword is similar to final, but the value of a const variable is determined at compile time. This means that the value of a const variable is the same for all objects, and it cannot be changed.
Here are a few key differences between final and const:
Scope: final variables are only accessible within the scope they are declared in, while const variables are accessible throughout the entire app.
Performance: const variables are evaluated at compile time, which means they are faster at runtime than final variables.
Modification: final variables can be modified within a constructor, while const variables cannot be modified at all.
