@override void autoFitColumn(BuildContext context, PlutoColumn column)

Implementation

@override
void autoFitColumn(BuildContext context, PlutoColumn column) {
  final String maxValue = refRows.fold('', (previousValue, element) {
    final value = column.formattedValueForDisplay(
      element.cells.entries
          .firstWhere((element) => element.key == column.field)
          .value
          .value,
    );

    if (previousValue.length < value.length) {
      return value;
    }

    return previousValue;
  });

  TextSpan textSpan = TextSpan(
    style: DefaultTextStyle.of(context).style,
    text: maxValue,
  );

  TextPainter textPainter = TextPainter(
    text: textSpan,
    textDirection: TextDirection.ltr,
  );

  textPainter.layout();

  EdgeInsets cellPadding =
      column.cellPadding ?? configuration.style.defaultCellPadding;

  resizeColumn(
    column,
    textPainter.width -
        column.width +
        (cellPadding.left + cellPadding.right) +
        2,
  );
