Dart Constants
Dart Constants
Dart Constants are immutable objects, which means that they can’t be changed or modified during the execution of the Dart program. It cannot be reassigned once we initialize the constant with a value. Dart will throw an exception if we try to modify the constant.
Dart Constants
The Dart constants can be defined using the following keywords:
- final keyword
- const keyword
These keywords can be used with or without a data type name.
final keyword
The final keyword denotes a single-time assignment of the variable. We can define the constant by using the final keyword. The general syntax to define a constant using the final keyword is as follows:
final constant_name;
final data_type constant_name
Example
final int MAX_ELEMENTS = 10;
const keyword
The const keyword represents the compile-time constant. We can define a constant by using the const keyword. The syntax is as follows:
const constant_name
const data_type constant_name
Example
const String bank_name=”Bank of America”;
