List V2 POC: Setup API for add/update/delete pseudo widget with pseudoWidgetReducer

[ashit-rath]

Part 1

In order to maintain the state of the pseudo widget like normal widgets a new reducer is introduced i.e pseudoWidgetReducer. As the pseudo widgets are added/removed on the fly based on a widget's rendering architecture, new APIs are to be introduced.

• AddPseudoWidget
• RemovePseudoWidget
• UpdatePseudoWidget

These three methods will update the individual widgets in the pseudo widget reducer.

Part 2

Make child widget properties dependant on templates

// Template
Select
    options - {{currentItem.colors}}
    defaultValue - {{currentItem.defaultColor}}

// Pseudo widget - List1_Select1_0
Select
    options - {(currentItem) => {
        currentItem.colors
      })(List1.listData[List1_Select1_0.__index])

    defaultValue - {{(currentItem) => {
        currentItem.colors
      })(List1.listData[List1_Select1_0.__index])}}

In the POC we were able to achieve the initial goals and on top of that we verified the widget operations on the List widget also works eg. drag/drop/resize, item size change etc.
