Answer 1

You have conflicting information in your code: a #UiConstructor and a #UiFactory (not conflicting actually, there's an order of precedence, but it can be confusing to the developer, i.e. you).
UiBinder will prefer the #UiFactory over the #UiConstructor, and your factory has no argument, so the teamNames attribute from your XML is tentatively mapped to a setTeamNames setter, which doesn't exist, hence the “Class CricketScores has no appropriate setTeamNames() method” error.
The problem is conceptual in your code: your UserDashboard is constructed with a list of team names that it passes to the CricketScores widget, so that widget shouldn't have a teamNames attribute in the XML.

I was getting same error and uiField(provided=true) was getting null but it got resolved when I created object of respective component in constructor
