    I found two best way to filter duplication.

First one:
RxList<String> myList = ["Canada", "India", "Canada"].obs;
print(myList.value.toSet().toList()); // ["Canada", "India"]

Second one:
if(!myList.contain(value)){
myList.add(value);
}

    You can use the Set to remove duplicates on your RxList which it’s values a List:

    RxList<String> myList = ["Canada", "India", "Canada"];

print(myList.value.toSet().toList()); // ["Canada","India"];
