avoid_ renaming_ method_ parameters
The parameter name '{0}' doesn't match the name '{1}' in the overridden method.
Description
#The analyzer produces this diagnostic when a method that overrides a method from a superclass changes the names of the parameters.
Example
#
The following code produces this diagnostic because the parameter of the
method
m
in
B
is named
b
, which is different from the name of the
overridden method's parameter in
A
:
class A {
void m(int a) {}
}
class B extends A {
@override
void m(int b) {}
}
Common fixes
#Rename one of the parameters so that they are the same:
class A {
void m(int a) {}
}
class B extends A {
@override
void m(int a) {}
}
