研究方向

先使用瀏覽器的 iPhone 和 iPad Pro 回應式預設重現 issue 中的 Slider 範例，然後將元素的位置與滑鼠拖曳的作用區域進行比較。報告中沒有指定原始檔案或測試；在較大的預設下，點擊和拖曳始終一致地使用可見的 slider 邊界即表示完成。

Description

I have a Slider component that works perfectly fine on browser simulated mobile phone environment (Chrome -> responsive "iPhone 6/7/8 Plus" preset). But when I use the slider on a bigger screen (Chrome -> responsive "iPad Pro" preset), the active range (where the slider starts moving with mouse drag) is far to the left from where the actual slider element is.

Let's say, the slider element is between width 750px and 900px:

  1. When I simply click on the slider, it goes automatically to maximumValue
  2. If I click & hold the slider, and then pull to the left side of the screen, nothing happens to the slider. It does not move.
  3. But when I reach the left edge of the screen (about 100px), then the slider starts to move with the mouse drag.

Here's a video. The first part is the "click makes it max value", and then comes the slider offset:

Reproducible Demo

const styles = StyleSheet.create({
  sliderBox: {
    flexDirection: 'row',
  },
});

interface Params {
  min: number;
  max: number;
  initialValue: number;
  bidToEdit: Bid;
  setter: Function; // This just passes the value to the parent, does not affect incoming params
}

export const CustomSlider = ({ min, max, initialValue, bidToEdit, setter }: Params) => {
  const [value, setValue] = useState<number>(initialValue);

  const sliderUpdated = (newValue: number) => {
    console.warn('Slider update to', newValue);
    setValue(newValue);
    setter(newValue);
  };

  return (
    <View style={styles.sliderBox}>
      <Slider
        value={value}
        step={1}
        onValueChange={sliderUpdated}
        minimumValue={min}
        maximumValue={max}
        minimumTrackTintColor={Colors.blue900Default}
        maximumTrackTintColor={Colors.blue50}
        thumbTintColor={Colors.blue900Default}
      />
      <SliderPoints value={value} updatePoints={sliderUpdated} min={min} max={max} />
    </View>
  );
};

I've also tried setting a maxWidth for the containing <View> but it doesn't change the behaviour.

I have also tried using onSlidingComplete and onSlidingStart, but the behaviour is still the same.
