fetchData method

  1. @protected
void fetchData()

Called to fetch new data.

This implementation simply delegates to the configured onFetch callback, if set, otherwise touch will be called to refresh the value.

Note: this method is provided for subclass customization and should not be called directly.

Implementation

@protected
void fetchData() {
  if (onFetch != null) {
    onFetch?.call(this);
  } else {
    touch();
  }
}
