This week in Flutter #33

#flutter #dart #news

Dart 2.15 has been announced , and OMG they are improving enums :

enum MyEnum {
   one, two, three
}
...
print(MyEnum.one.name);  // Prints "one".
print(MyEnum.values.byName('two') == MyEnum.two);  // Prints "true".

Maybe we will get Swift-like super enums one day.

And you have no idea how many times I declared a List with the 2.15 syntax, and it did not work:

var y = List; // Already supported.
var z = List<int>; // New in 2.15.
var z = typeOf<List<int>>(); // Pre-2.15 workaround.

Flutter 2.8 has also been announced , but my favourite news is the new Firebase UI widgets . Especially the FirestoreDataTable is going to save me so much time.

Vandad Nahavandipoor is very active on LinkedIn sharing tips about Flutter and Dart , and other frameworks and programming languages. The goal of this streamed event was to teach how BLoC works in Flutter, answering questions from the participants. I like the content Vandad share, I think the main reason is that Vandad is a real senior developer who also creates content, not the other way around.
