The class has the collection variable is not the "List" object.

Describe the bug
If the class has the collection variable is not the "List" object. Comparing is always return true.

To Reproduce
Steps to reproduce the behavior:

class E extends Equatable {
  final Map<String, int> map;

  E(this.map);
}

E e1 = E({"A": 1});
E e2 = E({"B": 2});
assert(e1 == e2); // return true

Expected behavior
assert(e1 != e2) //return true

Problem
https://github.com/felangel/equatable/blob/master/lib/src/equatable_utils.dart#L18-L24

Solution
Compare between 2 collections(List, Map, Set, v.v…) have to use Equality object(ListEquality, MapEquality, SetEquality, v.v…) in package:collection/collection.dart.
Don’t use “==” operator.

MapEquality mapEquality = MapEquality();
Map map1 = {"A": 1};
Map map2 = {"A": 1};
Map map3 = {"B": 2};
assert(mapEquality.equals(map1, map2)); //map1 == map2
assert(!mapEquality.equals(map2, map3)); //map2 != map3

@phamnhuvu-dev in your example I noticed you aren't passing the properties to the Equatable superclass.

class E extends Equatable {
  final Map<String, int> map;

  E(this.map) : super([map]); // missing call to super
}
