Hi guys! 😊 For those who enjoy developing games! I recently launched a package called Bonfire with the purpose of helping to build RPG-style games with Flutter + Flame. The result was very nice.For those who are curious to know how a game producing with Bonfire looks like, here is the example game:Android: https://play.google.com/store/apps/details?id=com.rafaelbarbosatec.darkness_dungeonIOS: https://apps.apple.com/us/app/darkness-dungeon/id1506675248Package: https://github.com/RafaelBarbosatec/bonfire

Review of my little helper widget called Selectable
I am very new to Flutter. At the moment I am working on a collection of re-useable widgets. I have a lot of widgets that are selectable meaning a user can tap/click on the widget and it somehow is in a selected state. This looks like this:The Button Types widget is selected in this example.You may notice that the text inside a selected widget is white whereas the text of non-selected widgets is usually black.And as I said - I have a lot of selectable widgets in my little library so I need to find a good solution for that.Initially most of my widgets simply had a selected property and if set to true the widget basically knew that it is selected. However this had some drawbacks. For example sometimes the descendant widgets need to know if it is inside a currently selected widget. So the value of selected would have to be passed from parent to all children and from all children to their children and so on. I think I found a better solution but I am unsure whether or not it is really better. I need your advice.```dart class Selectable extends InheritedWidget { const Selectable({ Key key, @required this.selected, @required Widget child, }) : assert(selected != null), assert(child != null), super(key: key, child: child);final bool selected;static Selectable of(BuildContext context) { return context.dependOnInheritedWidgetOfExactType<Selectable>(); }static bool current(BuildContext context, { bool fallback }) { final selectable = of(context); if(selectable != null) { return selectable.selected; } return fallback; }@override bool updateShouldNotify(Selectable oldWidget) => selected != oldWidget.selected; } ```Selectable is a helper widget that provides a selected-flag to descendants.You would use this widget to wrap another widget that can be selected by the user. You can then access the selected-state in any descendant like this:dart final selectable = Selectable.of(context) if(selectable != null) { if(selectable.selected) { print('selected yay'); } }Please note that selectable can be null if the widget is not wrapped with Selectable. The selected value can be determined in a more convenient way like this:dart final selected = Selectable.current(context, fallback: true) if(selected) print('selected yay');Here, selected is never null. It is either true or false. If your current widget is not wrapped by Selectable then selected will be have the same value as fallback.Is this a good idea? I mean it works and it allows all of my other widgets to change their text color (among other things) depending on whether or not they are inside something that is selected.Thanks.

Flutter Bloc Experiment
Hi folks.I did some small experiment with BloC pattern and I will be glad to hear your feedback. I have read that the best is to use BloC per screen, but what if instead of it I can have tree like structured BloCs. Here is basic example.So. In the application there can be lot of blocs, and any bloc responsible for one unit like widgets.ex.

1. UserSearchBloc 2. UserUpdateBloc 3. UserUpdateBloc 4. ProjectSearchBloc ... 

And when there is a need to combine some of the blocs, I can create manager which is responsible for children states synchronization.ex.

UserProjectManagerBloc( children: [ ProjectSearchBloc()..add(ProjectSearchFilterChanged()), UserManagerBloc( children: [ UserSearchBloc()..add(UserSearchFilterChanged()), UserDeleteBloc(), UserUpdateBloc(), ], ) ], ) class UserProjectManagerBloc extends BlocNode<BlocNodeEvent, UserProjectManagerState> { ... @override void onChildStateChange(BlocNodeState state) { if (state is UserDeleteSuccess) { getChild<ProjectSearchBloc>().add(ProjectSearchUserDeleted(state.id)); } } }
