EmpireDoubleProperty class Null safety
An EmpireProperty with similar characteristics of dart double objects
The underlying value cannot be null. For a nullable double empire property, use the EmpireNullableDoubleProperty.
You can perform most arithmetic operator on this (+, -, /, *).
Unary operators are not supported (++, --, +=, -=, etc)
When the value of this changes, it will send a EmpireStateChanged event by default. This includes automatically triggering a UI rebuild.
Example
late final EmpireDoubleProperty percentage;
percentage = createDoubleProperty(10.0);
print('${percentage + 5.2}'); //prints 15.2
