Setters must declare exactly one required positional parameterDRT-W1710
The analyzer produces this diagnostic when a setter is found that doesn't declare exactly one required positional parameter.
Examples
The following code produces this diagnostic because the setter s
declares
two required parameters:
class C {
set s(int x, int y) {}
}
The following code produces this diagnostic because the setter s
declares
one optional parameter:
class C {
set s([int x]) {}
}
Common fixes
Change the declaration so that there's exactly one required positional parameter:
class C {
set s(int x) {}
}
