onPressed: () async {
                              String? outputFile =
                                  await FilePicker.platform.saveFile(
                                allowedExtensions: null,
                                type: FileType.any,
                                dialogTitle:
                                    'Please select an output file:',
                                fileName: 'show',
                              );

                              if (outputFile == null) return;

                              if (!outputFile.endsWith('.pdf')) {
                                outputFile = '$outputFile.pdf';
                              }
                             
                            },

Just put a custom check if the outputFile doesn't have it.
