如何将远程配置集成到 flutter 应用程序？

Question

I have to integrate firebase remote config to my flutter app. From the searches in various sites, I couldn't find the complete solution.

class RemoteConfigurartion{
  Future<RemoteConfig> setupRemoteConfig() async {
    String value =null;
    final RemoteConfig remoteConfig = await RemoteConfig.instance;

    remoteConfig.setConfigSettings(RemoteConfigSettings(debugMode: false));
    remoteConfig.setDefaults(<String, dynamic>{
      'riddle': "off",
    });
    try {
      // Using default duration to force fetching from remote server.
      await remoteConfig.fetch(expiration: const Duration(seconds: 0));
      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');
    }
    return remoteConfig;
  }
}

This is what I found already. This the result I'm getting:

No implementation found for method RemoteConfig#instance on channel plugins.flutter.io/firebase_remote_config

But I have added all the plugins in the pubspec.yaml and in android gradle folder

Can anyone help me to find out a complete solution to integrate remote config to a flutter app?

Answer 1

Make sure that firebase_core is initialized, and for Android, google-services.json should be in the app folder. Aside from that, there doesn't seem to be any issues on your code. You might've missed some steps during set up.

If you've just added the plugins, it's best to run the app using restart instead of hot reload to ensure that all recently added plugins is included in the build.
