Getting Started 🚀

This project contains 3 flavors:

• development
• staging
• production

For the first step you need to set the environment variable first. Copy the assets/.env.example file to assets/.env then fill in all the required fields. To preview the environment variables like this:

BASE_URL_PROD = 
BASE_URL_STG  = 
BASE_URL_DEV  = 

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

*Flutter Starter works on iOS, Android, and Web.

Build App 🔥

To build APK desired flavor use the following commands:

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

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

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

And for builds for release, see the documentation according to the Android and iOS platforms.

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.

Working with Translations 🌐

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

Adding Strings

1. 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"
    }
}

2. 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"
    }
}

3. Use the new string

import 'package:flutter_starter/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

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

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

2. 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"
    }
}
