Disabled state

You can render the range selector in disabled state using enabled property. The default value of enabled property is true.

final double _min = 2.0;
final double _max = 10.0;
SfRangeValues _initialValues = SfRangeValues(5.0, 8.0);

final List<Data> _chartData = <Data>[
    Data(x:2.0, y: 2.2),
    Data(x:3.0, y: 3.4),
    Data(x:4.0, y: 2.8),
    Data(x:5.0, y: 1.6),
    Data(x:6.0, y: 2.3),
    Data(x:7.0, y: 2.5),
    Data(x:8.0, y: 2.9),
    Data(x:9.0, y: 3.8),
    Data(x:10.0, y: 3.7),
];

Widget build(BuildContext context) {
  return MaterialApp(

          body: Center(

                    child: SfCartesianChart(
                        margin: const EdgeInsets.all(0),

                                dataSource: _chartData,

                                    yValueMapper: (Data sales, int index) => sales.y)
                            ],
                        ),
                   ),
              ),
          )
      )
  );
}

class Data {
  Data({required this.x, required this.y});
  final double x;
  final double y;
}

Disabled color

You can change,

• The color of the active and inactive track in disabled state using the disabledActiveTrackColor and disabledInactiveTrackColor properties.
• The color of the active and inactive major ticks in disabled state using the disabledActiveTickColor and disabledInactiveTickColor properties.
• The color of the active and inactive minor ticks in disabled state using the disabledActiveMinorTickColor and disabledInactiveMinorTickColor properties.
• The color of the active and inactive dividers in disabled state using the disabledActiveDividerColor and disabledInactiveDividerColor properties.
• The color of the thumb in disabled state using the disabledThumbColor property.

NOTE

You must import the theme.dart library from the Core package to use SfRangeSelectorTheme.
