avoid_ setters_ without_ getters
Avoid setters without getters.
Details
#DON'T define a setter without a corresponding getter.
Defining a setter without defining a corresponding getter can lead to logical inconsistencies. Doing this could allow you to set a property to some value, but then upon observing the property's value, it could easily be different.
BAD:
class Bad {
int l, r;
set length(int newLength) {
r = l + newLength;
}
}
GOOD:
class Good {
int l, r;
int get length => r - l;
set length(int newLength) {
r = l + newLength;
}
}
