推荐答案

您可以使用Image.memory构造函数.

List<Asset> assets = ...; // use multi_image_picker to get the assets

return ListView.builder(
  padding: EdgeInsets.all(8.0),
  itemExtent: assets.length,
  itemBuilder: (BuildContext context, int index) {
    return Image.memory(assets[index].imageData.buffer.asUint8List());
  },
);
