Sliders Number Problem

[erenalpt]

Hi. Flutter is a great project. But I came across something strange while using sliders. The numbers are rolling. Is this normal? I created it as a double. However, this sounded very strange. Is it normal to round the numbers?

double sliders = 1;

        Text("Selected Sliders"),
        Slider(
          min: 0,
          value: sliders,
          max: 100,
          onChanged: (value) {
            setState(() {
              sliders = value;
            });
          },
          divisions: 100,
          label: sliders.toString(),
        ),

All done!

Hi @erenalpt,
What issue are you seeing exactly ? The screenshot you shared doesn't reveal much. I tried the official Slider example and was able to see the number slide properly without any issues.
Thanks.

Yes it is slipping. It just doesn't increase 1 to 1. I think it should go 28-29-30. But it looks like 28.xxxxx instead of 29 as in the picture. This happens at intervals, not for every number. I am using the Genymotion emulator.

@erenalpt I don't see the number slipping. Tested on latest beta using Slider official example as mentioned above.

Can you try on a physical device and see if you get same behavior ? Also please try the Slider official example.
Thanks.

I'll look at the slider image example. Why am I facing such a situation with the above code. I wonder this.

I tried it on Xiaomi Mi 8. I still have the same problem with the video. No code errors. Because my code, flutter is the same as the official document.

I am unable to replicate the issue on devices I tried, but it seems to be happening on certain devices. Keeping this issue open for further analysis.
