set method

@override void set(String key, dynamic value)

Sets a configuration value using dot notation.

Creates nested objects as needed. Useful for runtime configuration overrides or dynamic settings.

config.set('app.api_key', 'secret-key');
config.set('cache.enabled', true);
config.set('database.connections.max', 10);

Throws ConfigException if trying to set a nested property on a non-object value.

Implementation

@override
void set(String key, dynamic value) {
  final parts = key.split('.');
  final configName = parts.first;

  _runtimeDirtyConfigs.add(configName);

  if (!_config.containsKey(configName)) {
    _config[configName] = <String, dynamic>{};
  }

  var current = _config[configName];
  for (var i = 1; i < parts.length - 1; i++) {
    if (current is Map<String, dynamic>) {
      if (!current.containsKey(parts[i])) {
        current[parts[i]] = <String, dynamic>{};
      }
      current = current[parts[i]];
    } else {
      throw ConfigException('Cannot set nested property on non-object value');
    }
  }

  if (current is Map<String, dynamic>) {
    current[parts.last] = value;
    _cacheTimestamps[configName] = DateTime.now();
  } else {
    throw ConfigException('Cannot set property on non-object value');
  }
}
