Layouts body container can't contain other widgets

at the moment, my page page shows a google maps at the top of the page:

body: Container(
        height: 300,
        width: double.infinity,
        child: GoogleMap(
          mapType: MapType.normal,
          initialCameraPosition: _kGooglePlex,
          onMapCreated: (GoogleMapController controller) {
            _controller.complete(controller);
          },
        ),
      ),

I want to be able to add the rest of my code underneath that but it’s always complaining, what is teh best way to have a scrollable content and a map at the top of the page?!

SingleChildScrollView(
        child: Padding(
          padding: const EdgeInsets.all(12.0),
          child: Column(
            children: <Widget>[
              Card(
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: <Widget>[
                    ListTile(
                      title: Text("Title"),
                      subtitle: Text(widget.finds.title),
                    ),
                    ListTile(
                      title: Text("ID"),
                      subtitle: Text("${widget.finds.id}"),
                    ),
                    ListTile(
                      title: Text("Body"),
                      subtitle: Text(widget.finds.description),
                    ),
                    ListTile(
                      title: Text("Find"),
                      subtitle: Text("${widget.finds.primary_art}"),
                    ),
                    ListTile(
                      title: Text("Height"),
                      subtitle: Text("${widget.finds.height}"),
                    ),
                    ListTile(
                      title: Text("Width"),
                      subtitle: Text("${widget.finds.width}"),
                    ),
                    ListTile(
                      title: Text("Created By"),
                      subtitle: Text("${widget.finds.created_by}"),
                    ),
                  ],
                ),
              ),
            ],
          ),
        ),
      ),
