如何将 getter 与参数 dart/flutter 一起使用？

Question

I use this getter to make a list:

List<CabModel> get cabs() => cabsList.value;

and works. But now I need to pass a parameter to filter a list. Something like

List<CabModel> get cabs(String value) => cabsList.value;

I know, I can't pass parameter in getters, but how do it?

The getter only sends back copy of data, but cannot make any changes/filter stuff. You'd have to create a function that takes in the required parameters and returns the required value.

If you also want to filter and overwrite the existing data, make a setter as well.

List FilteredList(...){
  .../required filtering
  return list
}
