海外TECH	DEV Community	Using cubits for state management	https://dev.to/ramgendeploy/using-cubits-for-state-management-nmi	Using cubits for state managementAlright so I m making a revamp of my AiStickerMaker app and I have a functionality where you select an image from the gallery or the camera and a SliverAppBar widget will update with that image For this i was using a singleton to manage the state and passing that around but as you can guess it wasn t a great option it turns out changing the data in the singleton wasn t updating the state of the child widget So I decided to give blocs cubits a shot a decided this instead of provider because I thought that in the long run will be a better option Let s first see the implementation of the cubit I used for what I gathered a cubit is a simple form of a bloc as it extends BlocBase but it only holds one type of data this can be a complex class with multiple fields or just a String class ImageSelectedCubit extends Cubit lt String gt ImageSelectedCubit super void getNewImage ImageSource fileSource async final ImagePicker picker ImagePicker final XFile pickedFile await picker pickImage source fileSource emit pickedFile path void resetImage emit override void onChange Change lt String gt change super onChange change debugPrint change currentState debugPrint change nextState First we create the cubit class extending cubit and declaring that it holds a String We call the super of the class with this we set the initial stateThis one is the function that updates the state with the selected image here we call the pickImage function and with the result we call emit to update the value of the cubitA function to reset the stateThen with this we can debug the change of state Alright awesome right we have a cubit now what Well we need to provide this bloc in the right places and use a consumer to listen to the bloc MaterialApp home MultiBlocProvider providers BlocProvider create context gt ImageSelectedCubit child const HomePage Now the best way I saw how to do this is to wrap the home in the MateralApp widget with a MultiBlocProvider then we can state all of our providers inside of this widget and use them inside any children that follows this context Let s see how to actually use it and update a widgetFor this we need to use the BlocConsumer widget as said before a cubit is just a simpler Bloc so we can use any Bloc widget with it BlocConsumer lt ImageSelectedCubit String gt listener context state final imgCubit context read lt ImageSelectedCubit gt if state null showSnack Error context imgCubit resetImage builder context state final imgCubit context read lt ImageSelectedCubit gt return Image image FileImage File imgCubit state Here we create a BlocConsumer with the type of the cubit that we want and the type of data it holds here lt ImageSelectedCubit String gt Then this is optional but we can do data validation before we build the widget here we check if the image selected is null and we reset the value to an empty string Now in the builder function we can access the instance of the cubit using context read lt T gt T is the class of your cubit then reading state we access the value of the cubit And that s it I really liked the simplicity of cubits but I m sure I ll be diving deeper into Blocs for the rest of the app if you want to follow the development check out de YT vid	2022-07-31 22:26:58
