FdcExportColumn class

Maps one source field to its exported identity and presentation metadata.

fieldName identifies the value in each source row. Object-oriented writers can use key, tabular writers can use label as a header, and presentation-oriented writers can honor valueFormatter and textAlignment.

Constructors

FdcExportColumn({required String fieldName, String? key, String? label, FdcExportValueFormatter? valueFormatter, FdcExportTextAlignment textAlignment = FdcExportTextAlignment.left})
