ศึกษาการทำ integration test

screener

• This is a sample application.
• Uses MVVM pattern
• Tries to encourage the use of boundaries (by using the concept of packages)

Getting Started 🎯🎯

• Download the repo
• Make sure you are on the Flutter Stable Channel (1.22.6)

flutter channel stable
flutter upgrade

• Install dependencies, when asked, after downloading the project.
• Run the cmd

flutter run

• You should see the app working at this point..

Architecture 🏗🏗

• The app follows MVVM approach

• Their is a shared folder, which comprises of all the common entities.

• Common entites like assets, extensions, services etc

• Take a folder, let's say home

• It is broken down into components, models, utils (utilties if any), view and view_models

• Let's discuss each of them

Components

• They contain the building blocks of UI.
• A UI may comprise of a button, or card, or a list.
• All these items are created under their respective folders
• Let's say for a list component,

home/components/list/xyz.component.dart

Model (from MVVM)

• They are usually simple classes
• For instance, let's take home
• It would contain models folder, including all the models needed for home

home/models/xyz.model.dart

View (from MVVM)

• These are the screens visible to the user on their device.
• For instance, home would have views folder

home/view/xyz.view.dart

• We have 3 views

1. HomeView. Now home has 2 options (Egestas scleri) and (Consectur)
2. On click of Egestas scleri, you see the PellenView
3. On click of Consectur, you see the FringillaView

Templates

• They are some cases, when a view has a piece of UI, that is somewhat big.

• We extract those bits of UI, into the templates

• Let's say for the home view, we have a template as,

home/templates/carousel/xyz.template.dart

ViewModel (from MVVM)

• They help in transforming the data into models.
• For instance, home would have view_models folder

home/view_models/xyz.viewmodel.dart

Utils

• Any additional helpers or strings are put inside the utils
• For instance, home would have utils folder, containing all the strings needed

home/utils/strings.dart

Shared

• Their is a folder called shared, which includes all the common entities inside the app

• For instance, all the styles, colors are placed under styles

shared/styles/xyz.dart

• For instance, all the services are placed under the services folder

shared/services/xyz.service.dart

Data

• Sample data files are put inside the assets
• When needed they are fetched within the app.
