labelFormatterCallback property

  1. @Deprecated('Use `onLabelCreated` instead')
LabelFormatterCallback? labelFormatterCallback
final

Signature for formatting or changing the whole numeric or date label text.

  • The actual value without formatting is given by actualValue. It is either DateTime or double based on given initialValues or controller start and end values.
  • The formatted value based on the numeric or date format is given by formattedText.

This snippet shows how to set label format in SfRangeSelector.

SfRangeValues _initialValues = SfRangeValues(100.0, 10000.0); SfRangeSelector( min: 100.0, max: 10000.0, initialValues: _initialValues, interval: 9000.0, showLabels: true, showTicks: true, labelFormatterCallback: (dynamic actualValue, String formattedText) { return actualValue == 10000 ? '\$ $ formattedText +' : '\$ $ formattedText'; }, child: Container( height: 200, color: Colors.green[100], ), )
