Getting Started 🚀

Firebase

First, please create a Firebase project for development. After you create your project, remember to activate the following features: - Authentication with the anonymous option - Firestore with the rules in firestore.rules.

Next, use the instructions on Firebase website to set up the flutterfire_cli.

Allow it to override the lib/firebase_options.dart file with your project settings.

Running locally

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

$ flutter run -d chrome

*I/O Pinball works on Web for desktop and mobile.

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:pinball/l10n/l10n.dart';

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

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"
    }
}
