flutter_localized_string 0.0.2

NSLocalizedString inspired library for loading strings from json files.

flutter_localized_string

A new flutter plugin project.

Getting Started

This is library inspired by NSLocalizedString from iOS. Uses json files as language files eg. en.json , de.json

You have to add these to your pubspec.yaml:

flutter_localizations: 
    sdk: flutter

then you have to add within flutter: section:

assets:
    - assets/

When you're all set with pubspec file, you must put this in to your main.dart:

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      localizationsDelegates: [
        // ... app-specific localization delegate[s] here
        GlobalMaterialLocalizations.delegate,
        GlobalWidgetsLocalizations.delegate,
      ],
      supportedLocales: [
        const Locale('en', 'US'), // English
        // ... other locales the app supports
      ],

      title: "title",
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),      home: LocalizedWidget(widget: MyHomePage(title: "main_page_title")),
    );
  }
}

LocalizedWidget is responsible for wrapping up the class with FutureBuilder and enables plugin to load json file while loading widget tree.

Library usage

Once you did all of these steps. You should be able to use library as follows:

LocalizedString.by(key: "title")

while en.json looks like this:

{
    "title" : "Main title"
}
