How to use

  1. Left a VerticalArrangement or a VerticalScrollArrangement, set the width and the height as you like. Here is the sample:
  2. Before do anything like add a element, initialize it first: Choose only one of the initialize method
  3. Set the list The ”set” method required a list, and the list elements can be:
    • Single text element without icon: The list element here is just a Text, and it will be shown in the element
    • Single text element without icon(same with the one above): A sub-list with only one item is also allowed when creating a Single text element without icon.
    • Single text element with icon: The sub-list with two item will be proceed as a Single text element with icon. The first item is the icon path, when the second one is the text here.
    • Double text element with icon: A list with at least three item, is being recognize as a Double text elemtnt with icon. And only the very first three items will be used as the parameters here. They are: icon(path), Main-text, and Sub-text
