Some variables in flutter

Flutter variables are used to store data values that can be used throughout the application. The following are some common variables used in Flutter:

1. String: A sequence of characters enclosed in quotes, used to store text values.

Example:
“`
String name = “John”;
“`

2. int: A whole number used to store numerical values without decimal points.

Example:
“`
int age = 25;
“`

3. double: A number used to store numerical values with decimal points.

Example:
“`
double price = 9.99;
“`

4. bool: A data type used to store true or false values.

Example:
“`
bool isLoggedin = false;
“`

Flutter commands used to manipulate variables include:

1. var: A keyword used to declare a variable without specifying its data type.

Example:
“`
var name = “John”;
“`

2. final: A keyword used to declare a variable that cannot be changed after it is initialized.

Example:
“`
final int age = 25;
“`

3. const: A keyword used to declare a variable that is a compile-time constant and cannot be changed.

Example:
“`
const double price = 9.99;
“`

4. dynamic: A keyword used to declare a variable whose data type can be changed at runtime.

Example:
“`
dynamic value = “John”;
value = 25;
“`
