Question

Any suggestions for widgets that can be used for bumble graph like this?

Answer 1

你可以使用这个包https://pub.dev/packages/syncfusion_flutter_sliders，然后添加多个值，例如：

SfRangeValues _values = SfRangeValues(40.0, 80.0);

@override
Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: const Text('Syncfusion Flutter Range Slider'),
     ),
     body: SfRangeSlider(
        min: 0.0,
        max: 100.0,
        values: _values,
        interval: 20,
        showTicks: true,
        showLabels: true,
        enableTooltip: true,
        minorTicksPerInterval: 1,
        onChanged: (SfRangeValues values){
          setState(() {
            _values = values;
          });
        },
      ),
   );
}

虽然您可以根据需要向 SfRangeValues(40.0, 80.0) 添加值
