Flutter-ListWheelScrollView放大镜不能放大图像？

Question

我正在测试ListWheelScrollView，并注意到放大镜正在跳过图像和图标。 我们可以以某种方式改变它吗？ 这是一个样本。 另外，我们可以更改所选项目的颜色吗？例如，将当前缩放的项目涂上颜色，将其他项目涂成黑色和白色。

List<Widget> items = [
  ListTile(
    leading: Icon(Icons.local_activity, size: 50),
    title: Text('Activity'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_airport, size: 50),
    title: Text('Airport'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_atm, size: 50),
    title: Text('ATM'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_bar, size: 50),
    title: Text('Bar'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_cafe, size: 50),
    title: Text('Cafe'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_car_wash, size: 50),
    title: Text('Car Wash'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_convenience_store, size: 50),
    title: Text('Heart Shaker'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_dining, size: 50),
    title: Text('Dining'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_drink, size: 50),
    title: Text('Drink'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_florist, size: 50),
    title: Text('Florist'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_gas_station, size: 50),
    title: Text('Gas Station'),
    subtitle: Text('Description here'),
  ),
  ListTile(
    leading: Icon(Icons.local_grocery_store, size: 50),
    title: Text('Grocery Store'),
    subtitle: Text('Description here'),
  ),
];

        Container(
          height: 400,
          child: ListWheelScrollView(
            itemExtent: 75,
            children: items,
            useMagnifier: true,
            magnification: 1.5,
            physics: FixedExtentScrollPhysics(),
            diameterRatio: 4,
            perspective: 0.0000000001,
            onSelectedItemChanged: (index) => {print(index)},
          ),
        )

与此同时，Google又回到了github。将offAxisFraction设置为.5 https://github.com/flutter/flutter/issues/59163
