+
+A **`variable`** is a location in computer memory used to store references, usually for use in a program. Variables serve as symbolic names (identifiers) for values in the computer's memory. Variables allow programmers to manipulate and process data dynamically within their programs.
+
+## Syntax
+
+When declaring a variable in Dart, the type of variable goes first, followed by the name, and then the value:
+
+```pseudo
+type name = value;
+```
+
+- `type`: It can be any data type like `Int`, `String` or can also take the value `var`, `const`.
+- `value`: This is what the variable `name` represents. It corresponds to the data type `type`.
+
+> **Note:** The default type 'var' is inferred to be a `string`.
+
+If an object isn't restricted to a single type, specify the Object type (or dynamic if necessary):
+
+```pseudo
+Object name = 'value';
+```
+
+The Dart Language enforces sound null safety, allows to set default values and constants, and declares the late variables.
+
+## Example
+
+To display a constant name "Alex" one should write:
+
+```dart
+void main() {
+   const name = 'Alex';
+   print(name);
+}
+```
+
+The output for the above code will be:
+
+```shell
+Alex
+```
