Google Map widget is not displayed inside column about codelab-maps-platform-101-flutter

try wrapping googlemaps inside a Expanded widget that will autofill remaining space of Column or Row.

I fixed it like this -

Column(
children: [
SizedBox(
width: MediaQuery.of(context).size.width, // or use fixed size like 200
height: MediaQuery.of(context).size.height,
child: GoogleMap(
mapType: MapType.normal,
initialCameraPosition: CameraPosition(target: _center, zoom: 15),
))
])

But now new issues is there by placing google map in a column -
If placed in column, only zoom in map is working, that is also on double tap. No zooming out, no sliding in map to other location. Its like a static image of map.
