Question

我正在使用ImageCarousel库。从服务器获取的列表中有图像URL，现在我想在ImageCarousel中显示这些图像。我尝试了许多方法，但无法通过整个列表。我被这段代码所困扰，请帮助我。

这是我的代码：

List<NetworkImage> networkimages;

for(int i=0 ; i< modelList[0].listThumbnails.length; i++ ) {
    networkimages.add(new 
        NetworkImage(modelList[0].listThumbnails[i]));
}

new ImageCarousel(
    <ImageProvider>[
        new NetworkImage(CommonMethods.image_url + modelList[0].listThumbnails[0]),
        new NetworkImage(CommonMethods.image_url + modelList[0].listThumbnails[1],),
    ],
    interval: new Duration(seconds: 5),
    showCloseButtonOnZoom: true,
),

您只需将networkImages列表传递到ImageCarousel。像这样：

List<ImageProvider> networkimages = <ImageProvider>[];

for(int i=0 ; i< modelList[0].listThumbnails.length; i++ ) {
    networkimages.add(new 
        NetworkImage(modelList[0].listThumbnails[i]));
}

new ImageCarousel(
    networkimages,
    interval: new Duration(seconds: 5),
    showCloseButtonOnZoom: true,
),

如何在ImageCarousel中传递List？
