showAboutDialog Allow for additional buttons

[esDotDev]

When showing the AboutDialog, we would like to add a 3rd button "PRIVACY", there is currently no method to do this. It would be nice if it acception some list of extra btns, like TabBar does.

This sounds like a reasonable tweak to the API. Would you be willing to submit a PR for it?

Proposal for API

1. Allowing devs to pass the list of widgets as an action parameter

For an instance

    return showAboutDialog(
      context: context,
      applicationVersion: "v0.1.0",
      applicationLegalese: "Lorem Ipsum is simply ... ",
      applicationName: "Flutter App ",
      actions: [
        TextButton(onPressed: () => {}, child: const Text("PRIVACY POLICY"))  /// Newly added API
      ],
    );

2. Hard code a TextButton same as the existing action button in AboutDialog,

 actions: <Widget>[
/// Privacy Button Newly Added
        TextButton(
          child: Text("PRIVACY POLICY"), // THIS WILL BE COMING FROM MaterialLocalizations.of(context).viewLicensesButtonLabel
          onPressed: () {
          // Perform an action here

          },
        ),
        TextButton(
          child:
              Text(MaterialLocalizations.of(context).viewLicensesButtonLabel),
          onPressed: () {
            showLicensePage(
              context: context,
              applicationName: applicationName,
              applicationVersion: applicationVersion,
              applicationIcon: applicationIcon,
              applicationLegalese: applicationLegalese,
            );
          },
        ),
        TextButton(
          child: Text(MaterialLocalizations.of(context).closeButtonLabel),
          onPressed: () {
            Navigator.pop(context);
          },
        ),
      ],
