Here’s an example of creating a variable and initializing it:
Simple Variable
var name = 'Foo';
Variables store references. The variable called name contains a reference to a String object with a value of “Bob”.
Explicitly want to set the type? No problem
String Variable
String name = 'Foo';
Want to declare integers?
Integer variable
int count = 4;
Want to declare Floating point numbers?
Float/Double variable
double f = 1.0;
double is a language keyword
A simple program that uses variables
void main() {
int num=10;
double x = 10.0;
String y = 'Hello World!';
print(num);
print(x);
print(y);
}
That's all!
Next we will look into the dart language keywords set and explore a few keywords that change the way variables behave.
