Suggestion list doesn't inherit theme

[robertevans1]

Describe the bug The list of suggested places does not inherit the theme.

To Reproduce

Wrapping the place picker in a Theme, the list of suggested places is inheriting my main app theme (blue) but not the parent one (white).

Theme(
  data: ThemeData.from(
    colorScheme: ColorScheme(
      background: Colors.white,
    ),
  ),
  child: PlacePicker(
   ...
  ),
),

Expected behavior The list of suggested results should inherit the theme from it's parent.
