Dart by Example: Variables

1. main() {
2. // 'var' declares a variable.  dartanalyzer infers the type.
3. var a = "initial";
4. print(a);

6. // The type can also be declared:
7. num b = 42;
8. print(b);

10. // final variables cannot be changed once declared
11. final num c = 99;
12. print(c);

14. // const variables are compile-time constants
15. const double d = 44.00;
16. print(d);
17. }

1. $ dart variables.dart
2. initial
3. 42
4. 99
5. 44.0
