In this post, our agenda will be to focus on variables and data types in dart and a few fundamental concepts that should be kept in mind.
You can declare a variable with the keyword ‘var’ and 'dynamic' in the dart.
Example #1
where name is a variable that stores a string value, you can override the value with an integer or any other type of value.
You can also use type for a variable. In the above example, "myName" is a variable of String that can only store string values and if you try to override the value with a different type of value you will get a warning.
You can also use keywords like final, const, and dynamic to create a new variable. final and const are used to declare a variable whose value cannot be modified later.
Example with "final":
Example with "dynamic":
All variables in dart are a reference to objects which contain values and actions.
Dart contains six special types that are-
- Integers
- Floating-point numbers
- String
- Lists
- Maps
- booleans
We will go in-depth on types in the next article. Let me know if you like or dislike the article. I will improve upon the suggestions and feedbacks.
Happy learning, stay healthy and stay safe, thank you!!
