Remote Config Generator

A tool to generate Dart classes from a Firebase Remote Config templates for type safe and static typing. No more hardcoded values!

Usage

1. Add the dev_dependency

   dev_dependencies:
       remote_config_gen: 0.0.2
   

2. Download/Fetch the remoteconfig.template.json for your project

   firebase remoteconfig:get -o remoteconfig.template.json
   

3. Create a remote_config_gen.yaml file and define the configuration:

   input: remoteconfig.template.json
   output: lib/generated
   

4. Run the generator

   dart run remote_config_gen
   

5. Use the generated parameters:

   import 'package:remote_config_gen/remote_config_gen.dart';
   
   // It will return either the remote value or the default defined in the template
   int value = RemoteConfigParams.maxRetryCount.getValue();
   
   // It also accepts remote config groups
   bool isDark = RemoteConfigParams.uiSettings.darkMode.getValue();
   

6. (Optional) Change values in the template and update Firebase Remote Config

   firebase deploy --only remoteconfig
   

   Note: you can also manually do the changes in the Firebase dashboard and sync the changes again

Observing value changes

The generated RemoteConfigParam includes a method that returns a Stream, allowing you to observe Remote Config changes while the app is running.

RemoteConfigParams.uiSettings.darkMode.observeValue().listen((bool isDarkMode) {
    // Change the UI based on the new value
});

Limitations

The same limitations as Firebase Remote config applies. Meaning, you can only use the following types:

• String
• Boolean
• Numbers (int/double)
• JSON: a JSON string formatted value. It will be returned as String, you need to do the conversion yourself.
