Welcome to the colorful world of creating a Photo Booth! This guide will provide you with step-by-step instructions on how to set up a fun and interactive photo booth app using Flutter and Firebase, specifically tailored for “Google IO 2021”. Let’s dive in!

Getting Started

To launch the Photo Booth project, you have several convenient methods at your disposal. You can either use the launch configuration in your preferred IDE, like VSCode or Android Studio, or simply run the following command in your terminal:

sh
$ flutter run -d chrome

And voila! You now have a web-based Photo Booth running. How easy was that?

Running Tests

To ensure everything functions as expected, it’s essential to run both unit and widget tests. This helps you catch any bugs early in the process. Utilize this command to run the tests:

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

To view the generated coverage report, you can use lcov. Use these commands to generate and open your coverage report:

sh
# Generate Coverage Report
$ genhtml coverage/lcov.info -o coverage
# Open Coverage Report
$ open coverage/index.html

Working with Translations

Your Photo Booth project can reach a wider audience by including translations for multiple languages. This is achieved using flutter_localizations along with the official internationalization guide. Here’s how you can add new strings and translations:

Adding Strings

1. Open the file lib/l10n/arb/app_en.arb where you’ll find localizable strings. You will see lines similar to:

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

2. Add a new key-value pair along with a description. For instance, to add “Hello World”:

{
    "helloWorld": "Hello World",
    "@helloWorld": {
        "description": "Hello World Text"
    }
}

3. Then, import the localization package in your Dart file:

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

Adding Translations

For every supported locale, you will need to add a new ARB file in lib/l10n/arb. For example:

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"
    }
}

Troubleshooting Tips

If you encounter issues while setting up your Photo Booth or running the project, here are a few troubleshooting ideas:

• Make sure you have the latest version of Flutter installed. Run flutter upgrade to update.
• Check that all dependencies are correctly set up by running flutter pub get.
• If you face issues with translations, double-check your ARB files for syntax errors.
