How to pass a variable from home page to the overlaid widget? #1

This is not an issue, but more of a doubt or clarification. I have a variable that is given a value from inside a function in the homepage class. I want this variable data to be shown inside the overlaid widget. How do I do this? Could you help me please?

Hi @safal-305 , 

    Loader.appLoader.showLoader();
    Loader.appLoader.setText(errorMessage: 'data_here');

First line displays the overlay-loader, second line pass the data to loader-view, I'm passing the String as I'm showing Text widget.

In ValueListenableBuilder basically we listen to values and pass the desired values: 

                          ValueListenableBuilder<String>(
                            builder: (context, value, child) {
                              return Text(value);
                            },
                            valueListenable:
                                Loader.appLoader.loaderTextNotifier,
                          ),
