ProgressHUD (Heads Up Display)

It's helpful to give the user an indication that content is being loaded while the app sends a network request to get new data.

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,
    ),
);

Constructors Parameters

Parameter	Type	Description
child	Widget	Assign the widget need to show.
inAsyncCall	bool	Variable used to show or hide loader.
