海外TECH	DEV Community	Clean architecture of Flutter application. Part 2 - Practice	https://dev.to/george_andronchik/clean-architecture-of-flutter-application-part-2-practice-3562	Clean architecture of Flutter application Part PracticeHello everyone In the previous article we spoke about clean architecture concepts Now it s time to implement them For a good understanding we are going to develop a simple app The app receives info about solar flares and storms from the NASA API and presents it on the view Create ProjectFirst of all you have to install flutter You may check here the installation process After that let s create a project There are few ways to do it The basic way is to create a project by terminal command flutter create sunFlareNow we have an example of a project Let s modify it a bit by removing unwanted code and setting up directories So we ve created directories for each layer data domain and presentation and another one for the application layer which will contain application initialization and dependency injections Also we ve created files app dart app initialization and home dart main view of application Code of these files you can see below main import package flutter material dart import package sunFlare application app dart void main runApp Application app import package flutter material dart import package sunFlare presentation home dart class Application extends StatelessWidget override Widget build BuildContext context return MaterialApp title Flutter Demo theme ThemeData primarySwatch Colors blue visualDensity VisualDensity adaptivePlatformDensity home Home home import package flutter material dart class Home extends StatefulWidget override HomeState createState gt HomeState class HomeState extends State lt Home gt override Widget build BuildContext context return Scaffold The first step behind and now it s time to develop a domain DomainAs you can understand from the previous article the domain layer is the most important part of the application and it s the first layer you should design By the way if you design a backend system you just think about what entities aggregators should exist in the system and design it So far as we are designing the client application we already have some initial data which we fetch from the backend so we should take it into consideration when designing our domain entities However it doesn t mean we have to use the same data format as we receive from the backend Our application has its own business logic so we have to define entities that participate in this process Now then here is our domain level models import package meta meta dart class GeoStorm final String gstId final DateTime startTime GeoStorm required this gstId required this startTime import package meta meta dart class SolarFlare final String flrID final DateTime startTime final DateTime endTime final String classType final String sourceLocation SolarFlare required this flrID required this startTime this endTime required this classType required this sourceLocation We are going to implement a use case for collecting last solar activities geo storm and solar flare so let s define the model first import package meta meta dart import solar flare dart import geo storm dart class SolarActivities final SolarFlare lastFlare final GeoStorm lastStorm SolarActivities required this lastFlare required this lastStorm Fine Now we have business level models Let s define protocols for repositories returning these models import package meta meta dart import package sunFlare domain entities geo storm dart abstract class GeoStormRepo Future lt List lt GeoStorm gt gt getStorms required DateTime from required DateTime to import package meta meta dart import package sunFlare domain entities solar flare dart abstract class SolarFlareRepo Future lt List lt SolarFlare gt gt getFlares required DateTime from required DateTime to And as I ve promised here is a use case import package sunFlare domain entities solar activities dart import package sunFlare domain repos geo storm repo dart import package sunFlare domain repos solar flare repo dart class SolarActivitiesUseCase final GeoStormRepo geoStormRepo final SolarFlareRepo solarFlareRepo SolarActivitiesUseCase this geoStormRepo this solarFlareRepo Future lt SolarActivities gt getLastSolarActivities async final fromDate DateTime now subtract Duration days final toDate DateTime now final storms await geoStormRepo getStorms from fromDate to toDate final flares await solarFlareRepo getFlares from fromDate to toDate return SolarActivities lastFlare flares last lastStorm storms last Good Now let me clarify what we ve done just now First of all we designed the data models we needed for our use case After that we found out where to get those models from and defined repository protocols Finally we implemented a direct use case which function is to return the last solar activities It calls functions of repositories extracts and collects last solar activities and returns it The tree of domain layer directory should looks like this We ve just implemented the core of our application ーthe business logic Now it s time to take care of the data layer DataThe first step is quite similar to the first step of the previous section we are going to design the data models which will be fetched from the network import package sunFlare domain entities geo storm dart class GeoStormDTO final String gstId final DateTime startTime final String link GeoStormDTO fromApi Map lt String dynamic gt map gstId map gstID startTime DateTime parse map startTime link map link import package sunFlare domain entities solar flare dart class SolarFlareDTO final String flrID final DateTime startTime final DateTime endTime final String classType final String sourceLocation final String link SolarFlareDTO fromApi Map lt String dynamic gt map flrID map flrID startTime DateTime parse map beginTime endTime map endTime null DateTime parse map endTime null classType map classType sourceLocation map sourceLocation link map link DTO means Data Transfer Object It s an usual name for transport layer models The models implement constructors parsing JSON The next code snippet contains the implementation of NasaService which is responsible for NASA API requests import package dio dio dart import package sunFlare data entities geo storm dto dart import package sunFlare data entities solar flare dto dart import package intl intl dart class NasaService static const BASE URL final Dio dio Dio BaseOptions baseUrl BASE URL Future lt List lt GeoStormDTO gt gt getGeoStorms DateTime from DateTime to async final response await dio get DONKI WS get GST queryParameters startDate DateFormat yyyy MM dd format from endDate DateFormat yyyy MM dd format to return response data as List map i gt GeoStormDTO fromApi i toList Future lt List lt SolarFlareDTO gt gt getFlares DateTime from DateTime to async final response await dio get DONKI WS get FLR queryParameters startDate DateFormat yyyy MM dd format from endDate DateFormat yyyy MM dd format to return response data as List map i gt SolarFlareDTO fromApi i toList The service contains methods calling API and returning DTO objects Now we have to extend our DTO models We are going to implement mappers from data layer models to domain layer models import package sunFlare domain entities geo storm dart class GeoStormDTO final String gstId final DateTime startTime final String link GeoStormDTO fromApi Map lt String dynamic gt map gstId map gstID startTime DateTime parse map startTime link map link extension GeoStormMapper on GeoStormDTO GeoStorm toModel return GeoStorm gstId gstId startTime startTime import package sunFlare domain entities solar flare dart class SolarFlareDTO final String flrID final DateTime startTime final DateTime endTime final String classType final String sourceLocation final String link SolarFlareDTO fromApi Map lt String dynamic gt map flrID map flrID startTime DateTime parse map beginTime endTime map endTime null DateTime parse map endTime null classType map classType sourceLocation map sourceLocation link map link extension SolarFlareMapper on SolarFlareDTO SolarFlare toModel return SolarFlare flrID flrID startTime startTime classType classType sourceLocation sourceLocation And finally it s time to implement repositories which protocols are in the domain layer import package sunFlare data services nasa service dart import package sunFlare domain entities geo storm dart import package sunFlare domain repos geo storm repo dart import package sunFlare data entities geo storm dto dart class GeoStormRepoImpl extends GeoStormRepo final NasaService nasaService GeoStormRepoImpl this nasaService override Future lt List lt GeoStorm gt gt getStorms DateTime from DateTime to async final res await nasaService getGeoStorms from to return res map e gt e toModel toList import package sunFlare data services nasa service dart import package sunFlare domain entities solar flare dart import package sunFlare domain repos solar flare repo dart import package sunFlare data entities solar flare dto dart class SolarFlareRepoImpl extends SolarFlareRepo final NasaService nasaService SolarFlareRepoImpl this nasaService override Future lt List lt SolarFlare gt gt getFlares DateTime from DateTime to async final res await nasaService getFlares from to return res map e gt e toModel toList The constructors of repositories accept NasaService Methods call requests map DTO models to domain models by mappers we have just realized and return domain models to the domain layer This is how the Data directory should look like now User InterfaceAlmost there Domain and Data are behind now it s time for Presentation Layer I am not going to write a lot about presentation layer architectures in this article There is a range of variants and if you are interested in this topic please let me know in the comments As long as we decided to use the MVVM pattern for presentation layer architecture let s add dependencies for RX flutter mobx any flutter mobx anyAlso we need to add packets to dev dependencies to generate files that allow us to use annotations observable computed action Just a bit of syntax sugar dev dependencies mobx codegen any build runner anyWe already have the view ーHome Just add the file called home state dart nearby This file will contain viewModel which in flutter is usually called state for some reason And add the code to the file import package mobx mobx dart import package sunFlare domain use cases solar activities use case dart import package sunFlare domain entities solar activities dart part home state g dart class HomeState HomeStateBase with HomeState abstract class HomeStateBase with Store HomeStateBase this useCase getSolarActivities final SolarActivitiesUseCase useCase observable SolarActivities solarActivities observable bool isLoading false action Future lt void gt getSolarActivities async isLoading true solarActivities await useCase getLastSolarActivities isLoading false Nothing special here We call our use case in the constructor Also we have two observable properties ーsolarActivities and isLoading solarActivities is just the model returned by the use case isLoading shows us if the request is in progress The view will subscribe to these variables soon To generate class home state g dart to use obsevable annotations just call the command in terminal flutter packages pub run build runner buildLet s come back to our view ーhome dart and update it import package flutter material dart import package flutter mobx flutter mobx dart import package sunFlare presentation home state dart class Home extends StatefulWidget HomeState homeState Home Key key required this homeState super key key

solarActivities lastStorm startTime override Widget build BuildContext context return Scaffold body SafeArea child body HomeState object in initializator as an argument and extremely simple UI If isLoading true we show an activity indicator If not we present data of the last solar activities ApplicationFinish him We have everything we need now it s time to keep it together The application layer includes dependency injections and initializations Create directory dependencies in the application directory and add two files there import package sunFlare domain repos geo storm repo dart
