use_setters_to_change_properties
The method is used to change a property.
Description
#The analyzer produces this diagnostic when a method is used to set the value of a field, or a function is used to set the value of a top-level variable, and nothing else.
Example
#The following code produces this diagnostic because the method setF
is used to set the value of the field _f
and does no other work:
dart
class C {
int _f = 0;
void setF(int value) => _f = value;
}
Common fixes
#Convert the method to a setter:
dart
class C {
int _f = 0;
set f(int value) => _f = value;
}
