Slider active or inactive color buggy/turning transparent?-CodePudding

I'm having trouble with setting the Slider widget's color, be it the active or inactive color.

Color color = const Color(0x00ff9f1c);

Slider(
              value: sliderValue,
              activeColor: color,
              min: 0.0,
              max: 100.0,
              divisions: 2000,
              label: sliderValue.toStringAsFixed(2),
              onChanged: (value) {
                setState(() {
                  sliderValue = value;
                  InputVariables.distance = sliderValue;
                });
              }),

This causes my slider to go transparent in the active color section like this:

If I set the activeColor to a Colors.somecolor it works, so is it an issue with the Color class being incompatible? I have tried Hot reloading, restarting, and rebuilding.

I am trying to get the activeColor to work without this bug, looking something like this as the result (not the exact color I want), but by using my color const I have declared and initialized.

CodePudding user response：

As you attached image, use activeColor and inactiveColor to get the result.

Slider(
    value: sliderValue,
    activeColor: Colors.amber,
    //inactiveColor: color,
    inactiveColor: Colors.blue.shade100,
    min: 0.0,
    max: 100.0,
    label: sliderValue.toStringAsFixed(2),
    divisions: 2000,
    onChanged: (value) {
      setState(() {
        sliderValue = value;
      });
    }),
