v0.12.0

• Breaking Offstage support. By default Offstage widgets are not found by spot<W>(). Use spotOffstage().spot<W>() to find them. spotAllWidgets() returns onstage and offstage widgets. Use .overrideWidgetPresence(WidgetPresence.offstage) to modify a WidgetSelector to search for offstage, onstage or combined #45
• New: act.enterText(spot<TextField>(), 'Hello World!') allows to enter text into a EditableText #51
• Negating parents is not yet supported (spot<ListView>().withParent(spot<Scaffold>().atMost(0))). It now throws to prevent unexpected behavior. #50
• act.tap(spot<ElevatedButton>()) now pumps automatically after the tap #52
