Firebase Remote config in flutter

1-- create Model as you did in the console:

class RemoteConfigDataModel {
bool? isForceUpdate;
bool? inMaintenanceMode;

RemoteConfigDataModel({
this.isForceUpdate,
this.inMaintenanceMode,

});

RemoteConfigDataModel.fromJson(dynamic json) {
isForceUpdate = json['isForceUpdate'] ?? false;
inMaintenanceMode = json['inMaintenanceMode'] ?? false;

}

Map<String, dynamic> toJson() {
final map = <String, dynamic>{};
map['isForceUpdate'] = isForceUpdate;
map['inMaintenanceMode'] = inMaintenanceMode;

}

2-- put global instance in the main:

RemoteConfigDataModel remoteConfigDataModel = RemoteConfigDataModel();

3--

Future<FirebaseRemoteConfig> setupFirebaseRemoteConfig() async {
final FirebaseRemoteConfig remoteConfig = FirebaseRemoteConfig.instance;

try {
remoteConfig
.setConfigSettings(RemoteConfigSettings(fetchTimeout: Duration.zero, minimumFetchInterval: Duration.zero));
await remoteConfig.fetch();
await remoteConfig.fetchAndActivate();
} catch (e) {
throw language.firebaseRemoteCannotBe;
}
remoteConfigDataModel = RemoteConfigDataModel.fromJson(jsonDecode(remoteConfig.getString("USER_CHANGE_LOG")));
return remoteConfig;

4-- finally do not forget to call setupFirebaseRemoteConfig() at the main.dart
