Json to strings.dart

[Tkko]

What does this change?

Many developers use json based translations, this PR adds strings.dart class generator from json files.

pubspec.yaml

flutter_gen:
  output: lib/gen/
  line_length: 80

  strings:
    enabled: true
    class_name: Strings
    inputs:
      - assets/translations/en.json

run: flutter packages pub run build_runner build

From en.json:

{
  "appTitle": "Title",
  "contributor": "Tornike Kurdadze (Tkko)"
}

To strings.gen.dart

class Strings {
  Strings._();

  static const appTitle = 'appTitle';
  static const contributor = 'contributor';
}

@wasabeef Any thought about this?

@Tkko Thank you for your PR. Could you tell me a little more about the use case? In general, I think We're using flutter_localizations.

This is helpful if you are using json based localizations, checkout the article for reference. https://medium.com/@rafavinnce/flutter-internationalization-the-easy-way-using-provider-and-json-986eb5d76822

In short, you have translation files, en.json, ka.json, ... and you are accessing the translated string by the key, and with this PR keys will be extracted as constants.

@wasabeef The idea of this PR seems to be inspired Android localization R.string.xxx_yyy, and the Flutter localization is using AppLocalizations.instance.text('page_one'),
