When we start any network call we will set isApiCallProcess = true, when the network call completed we will set back isApiCallProcess = false

bool isApiCallProcess = false;
return Scaffold(
    appBar: _buildAppBar(),
    body: ProgressHUD(
        child: pageUI(),
        inAsyncCall: isApiCallProcess,
        opacity: 0.3,
    ),
);

    initialValue: this.productModel.images.map((e) => e.src).toList(), //for showing images from collection
