downloadReport method

Future<void> downloadReport()

Programmatically triggers the internal download/export logic.

This allows you to initiate an Excel export or file download from a button located outside of the ReportMaker widget.

Implementation

Future<void> downloadReport() async {
  if (_downloadCallback != null) {
    await _downloadCallback!();
  } else {
    debugPrint("NRB Warning: Controller is not attached or download is unavailable.");
  }
}
