How to show a spinner during network image loading ?

[dariocavada]

I'm using flutter cached_network_image component for panoramas. Some panorama have quite big size (8-12Mb). Any idea how to show a spinner to show the downloading phase ?

found a solution:

CachedNetworkImage(
          imageUrl:
              'your image url',
          fit: BoxFit.cover,
          cacheManager: CustomCacheManager.instance,
          placeholder: (context, url) => Container(
            child: Center(
              child: CircularProgressIndicator(),
            ),
          ),
          imageBuilder: (context, imageProvider) => Panorama(
            animSpeed: 1.0,
            sensorControl: SensorControl.Orientation,
            child: Image(
              image: imageProvider,
            ),
          ),
        )
