AppBar Dropdown is an attractive UI element that allows for navigation via a dropdown menu in the AppBar.

• Looks and behaves just like a beautiful AppBar Dropdown menu should
• Configurable
• Works over the top of a WebView

AppbarDropdown is used by setting it as the value for the flexibleSpace property of your Scaffold's AppBar.

    Scaffold(
        appBar: AppBar(
            flexibleSpace: AppbarDropdown(
                items: [ for (var i=0;i<100;i++) "User $i" ],
                selected: "User 2",
                title: ( (user) => user.toString() ),
                onClick: ( (user) => print(user) ),
            ),

• items - An array of any object type
• title - A function that takes an object of the type in the items array and outputs a string title to display in the list, and in the heading. (This might look something like title: ( (p) => (p as MyAppPageObject).pageName ))

• selected - The initial default value, of the same type as the items in the array
• onClick - A function that takes the same type of object, and does something with it (eg. change to new app page content, if the objects are page type Widgets)

• dialogInsetPadding - Specifies the padding for the dropdown
• dropdownAppBarColor - Specifies the colour of the dropdown, including the header
