EmpireDoubleProperty class
An EmpireProperty with similar characteristics of dart double objects
The underlying value cannot be null. For a nullable double empire property, use the EmpireNullableDoubleProperty.
When the value of this changes, it will send a EmpireStateChanged event by default. This includes automatically triggering a UI rebuild.
Example
final percentage = EmpireDoubleProperty(10.0);
print('${percentage.add(5.2)}'); //prints 15.2
