My App

Design

I could probably finish this in one day, but not following a clean and maintaible code. So I decided to takcle this as a continues project rather than just a challenge.

Design: Mostly in my work I start knowing first the zoom in and out of application. knowing the features, making wireframes with UI/UX Designer. Then copy the UI without functionality if the design pass, I proceed in adding bussiness logic. Finish v1 test ,develop cycle.

I can decide the UI/UX design as long as our app is not complex..

Back end approach

Our c# back end should offer:

Authentication
Manage Images (here we may use 3rd party library to store our images depends...)
Manage Dates(im not sure yet how the calendar will be used)

Flutter Front end

Test app

Getting Started 🚀

This project contains 3 flavors:

development
staging
production

To run the desired flavor either use the launch configuration in VSCode/Android Studio or use the following commands:

# Development
$ flutter run --flavor development --target lib/main_development.dart

# Staging
$ flutter run --flavor staging --target lib/main_staging.dart

# Production
$ flutter run --flavor production --target lib/main_production.dart

*My App works on iOS, Android, Web, and Windows.

Running Tests 🧪

To run all unit and widget tests use the following command:

$ flutter test --coverage --test-randomize-ordering-seed random

To view the generated coverage report you can use lcov.

# Generate Coverage Report
$ genhtml coverage/lcov.info -o coverage/

# Open Coverage Report
$ open coverage/index.html

Working with Translations 🌐

This project relies on flutter_localizations and follows the official internationalization guide for Flutter.

Adding Strings

To add a new localizable string, open the app_en.arb file at lib/l10n/arb/app_en.arb.

{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    }
}

Then add a new key/value and description

{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    },
    "helloWorld": "Hello World",
    "@helloWorld": {
        "description": "Hello World Text"
    }
}

Use the new string

import 'package:my_app/l10n/l10n.dart';

@override
Widget build(BuildContext context) {
  final l10n = context.l10n;
  return Text(l10n.helloWorld);
}

Adding Supported Locales

Update the CFBundleLocalizations array in the Info.plist at ios/Runner/Info.plist to include the new locale.

    ...

    <key>CFBundleLocalizations</key>
	<array>
		<string>en</string>
		<string>es</string>
	</array>

    ...

Adding Translations

For each supported locale, add a new ARB file in lib/l10n/arb.

├── l10n
│   ├── arb
│   │   ├── app_en.arb
│   │   └── app_es.arb

Add the translated strings to each .arb file:

app_en.arb

{
    "@@locale": "en",
    "counterAppBarTitle": "Counter",
    "@counterAppBarTitle": {
        "description": "Text shown in the AppBar of the Counter Page"
    }
}

app_es.arb

{
    "@@locale": "es",
    "counterAppBarTitle": "Contador",
    "@counterAppBarTitle": {
        "description": "Texto mostrado en la AppBar de la página del contador"
    }
}

Generating Translations

To use the latest translations changes, you will need to generate them:

Generate localizations for the current project:

flutter gen-l10n --arb-dir="lib/l10n/arb"

Alternatively, run flutter run and code generation will take place automatically.
