[1.0.0-dev] -

Changed

• No need package dependencies: We decided to remove all dependencies and create a new state management from scratch.

• Controller now is Context: ReactterController has been replaced by ReactterContext, which are the classes that going to manage our states.

    class AppContext extends ReactterContext {}
  

Added

• Two ways to manage state: You can control the listeners from context like this:

    class AppContext extends ReactterContext {
        /* You can create the state here and add it to dependencies in 
        constructor with listenHooks() */
        final username = UseState<String>("");
  
        AppContext(){
            listenHooks([username]);
        }
  
        /* But we recommend to give the context to the state this way:
        With this, you no longer need to put it in listenHooks()
       which is cleaner */
        late final firstName = UseState<String>("Leo", context: this);
        late final lastName = UseState<String>("León", context: this);
    }
  

• Added UseProvider widget: UseProvider provide all ReactterContext to his children.

    UseProvider(
      contexts: [
        UseContext(
          () => AppContext(),
          init: true,
        ),
      ],
      builder: (context, _) {
        // Get all the states listeners of context.
        final appContext = context.of<AppContext>();
  
        // Get the listener of an specific state to rebuild.
        final appContext = context.of<AppContext>((ctx) => [ctx.userName]);
  
        // Read all the states, but no rebuild when change.
        final appContextStatic = context.ofStatic<AppContext>();
  
        return Text(appContext.username.value);
      }
    );
  
  

• Remove UseEffect widget: This widget has been replaced by a class called UseEffect. It has exactly the same functionality as the React Hook, when a dependency changes, executes the callback parameter.

    UseEffect((){
  
      userName.value = firstName + lastName;
  
    }, [firstName, lastName]);
  

-Note*: UseEffect has to be called inside context constructor.

• Added custom Hooks: You can create your own hooks with mixin inherit from ReactterHook.

   mixin UseCart on ReactterHook {
       late final cart = UseState<Cart?>(null, context: this);
  
       addProductToCart(Product product) {
           final oldProducts = cart.value.products;
  
           cart.value = cart.value?
               .copyWith(products: [...oldProducts, product]);
       }
   }
  
  

• Added UseAsyncState class: If you need an async state, you can use this:

  
  class AppContext extends ReactterContext {
      ...
  
       late final userName =
           UseAsyncState<String>("Init state", fillUsername, context: this);
  
       Future<String> fillUsername() async {
           final userFromApi = await getUserName();
  
           return userFromApi;
       }
  
       ...
  }
  
  

• Added UseAsyncState.when function: Added this function to controll the async flow from UseAsyncState:

   ...
   ),
   userContext.userName.when(
         
       // Base state
       standby: (value) => Text("Standby: " + value),
       // When is executing the async code
       loading: () => const CircularProgressIndicator(),
       // When the async code has finished
       done: (value) => Text(value),
       // When it throw an error
       error: (error) => const Text(
           "Unhandled exception",
           style: TextStyle(color: Colors.red),
       ),
   ),
   ...
  
  

• Added lifecycle methods to ReactterContext:

   @override
   awake() {
       // Executes when the instance starts building.
   }
  
   @override
   willMount() {
       // Before the dependency widget will mount in the tree.
   }
  
   @override
   didMount() {
       // After the dependency widget did mount in the tree.
   }
  
   @override
   willUnmount() {
       // When the widget removes from the tree.
   }
