How do I create a type alias
You can't define alias. For your case you can use DelegatingList from quiver to define Directives
:
import 'package:quiver/collection.dart';
class Directives extends DelegatingList<String> {
final List<String> delegate = [];
}
It is possible now via an empty mixin
mixin ToAlias{}
class Stuff<T> {
T value;
Stuff(this.value);
}
class StuffInt = Stuff<int> with ToAlias;
main() {
var stuffInt = StuffInt(3);
}
EDIT 2.13
It looks likely that unreleased 2.13 will contain proper type aliasing without the need of a mixin.
typedef IntList = List<int>;
IntList il = [1,2,3];
