Flutterfire: [remote_config] Unable to retrieve neested config. (" are striped away)

[bounty1342]

Describe the bug
remoteConfig.getString('locale'); is removing the quote of the included string.

To Reproduce

Future<RemoteConfig> setupRemoteConfig() async {
  final RemoteConfig remoteConfig = await RemoteConfig.instance;
  // Enable developer mode to relax fetch throttling
  remoteConfig.setConfigSettings(RemoteConfigSettings(debugMode: true));
  remoteConfig.setDefaults(<String, dynamic>{
    "welcome": "default welcome",
    "hello': 'default hello",
    "locale": {
        "languageCode": "en",
        "countryCode": "US"
      },
  });
  return remoteConfig;
}

Expected behavior

    String jsonLocaleConfig = remoteConfig.getString('locale');
    _localeConfig = json.decode(jsonLocaleConfig);

Same here :/

adding the very convenient method getJsonValue(key) would be nice too... just saying :)

Hey @bounty1342 could you explain:

remoteConfig.getString('locale'); is removing the quote of the included string.

Not entirely sure what is happening?

[bounty1342]

Thanks for getting back to me.

  String jsonDefaultConfig = await _loadLocaleDefautConfig();
  print('Json of default config : $jsonDefaultConfig');
  Map<String, dynamic> defaultConfig = json.decode(jsonDefaultConfig);
  print(
      'Map<String, dynamic>  of default config : ${defaultConfig['locale']}');
  remoteConfig.setDefaults(defaultConfig);
  print('String of remoteConfig : ${remoteConfig.getString('locale')}');
  try {
    await remoteConfig.fetch(expiration: const Duration(hours: 5));
    await remoteConfig.activateFetched();
  } on FetchThrottledException catch (exception) {
    // Fetch throttled.
    print(exception);
  } catch (exception) {
    print('Unable to fetch remote config. Cached or default values will be '
        'used');
  }
  print(
      'String of remoteConfig after fetch: ${remoteConfig.getString('locale')}');

  print('try to encode it: ${json.encode(remoteConfig.getString('locale'))}');
  print('try to decode it: ${json.decode(remoteConfig.getString('locale'))}');
  return remoteConfig;

I/flutter (25662): Json of default config : {
I/flutter (25662):  "appName": "test",
I/flutter (25662):  "dark_mode": false,
I/flutter (25662):  "cacheActivated": true,
I/flutter (25662):  "locale": {
I/flutter (25662):      "languageCode": "en",
I/flutter (25662):      "countryCode": "US"
I/flutter (25662):  },
I/flutter (25662): Map<String, dynamic>  of default config : {languageCode: en, countryCode: US}
I/flutter (25662): String of remoteConfig : {countryCode=US, languageCode=en}
I/flutter (25662): Unable to fetch remote config. Cached or default values will be used
I/flutter (25662): String of remoteConfig after fetch: {countryCode=US, languageCode=en}
I/flutter (25662): try to encode it: "{countryCode=US, languageCode=en}"
E/flutter (25662): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: FormatException: Unexpected character (at character 2)
E/flutter (25662): {countryCode=US, languageCode=en}

We pass a to remoteConfig.setDefaults(defaultConfig); where local is a json, then remoteConfig.getString('locale') produce a String that is not a Json. (Making defaultConfig useless)

Note that the same config work fine when fetched, it's a copy and paste ! But if the user has no internet and no cache for the default config, it will fail to decode it.

Let me know if you need any more info, I will be glad to sort this one out.

PS : I'm on discord, if you need more reactivity.

Hi,

Any progress on this one ?

[bounty1342]

@Ehesp Any chance to look at this one ?

My first time users with no internet would be stuck otherwise... Not a very good introduction...
