Answer 1

Use Dialog widget over your ImageNetwork widget. This will resolve your issue.


onTap:() {
        showDialog(context: context, builder: (BuildContext context) {
          return Dialog(
           child: ImageNetwork(image: data['image'].toString(),
            height: 400,
            width: 400,
            duration: 1000,
            curve: Curves.easeIn,
            onPointer: true,
            fitAndroidIos: BoxFit.cover,
            fitWeb: BoxFitWeb.cover,
            borderRadius: BorderRadius.circular(50),
            onLoading: const CircularProgressIndicator(color: Colors.amber,),),`enter code here`);
        });
      }
