duplicate_field_formal_parameter
The field '{0}' can't be initialized by multiple parameters in the same constructor.
Description
#The analyzer produces this diagnostic when there's more than one initializing formal parameter for the same field in a constructor's parameter list. It isn't useful to assign a value that will immediately be overwritten.
Example
#The following code produces this diagnostic because this.f
appears twice in the parameter list:
class C {
int f;
C(this.f, this.f) {}
}
Common fixes
#Remove one of the initializing formal parameters:
class C {
int f;
C(this.f) {}
}
