Flutter google_maps_flutter package blocking alertDialog - google-maps

Question

I am currently using the google_maps_flutter package, and I am placing it within a stack and overlaying it with a button. When the button is pressed, an alert should pop up.
The problem I am currently having is that it works upon first load, but if I exit the app, putting it in the background, and I reenter the app, the alertDialog is no longer showing up. It exists on the screen because I am unable to move the map, and I have to click the area where the button would normally be, but it is not visible.
Any ideas on what's going on?
#override
Widget build(BuildContext context) {
return new Scaffold(
body: new Center(
child: new Stack(
children: <Widget>[
new Container(
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
child: new Opacity(
opacity: opacity,
child: new GoogleMap(
onMapCreated: initializeMap,
options: GoogleMapOptions(
//trackCameraPosition: true,
compassEnabled: true,
myLocationEnabled: true,
),
),
),
),
new Align(
alignment: new Alignment(0, 1),
child: new GestureDetector(
onTap: () {
alert();
},
child: new Image.asset(
'assets/test.png',
height: 150.0,
fit: BoxFit.cover,
),
),
),
],
),
),
),
}
alert() {
return showCupertinoDialog(
context: context,
builder: (BuildContext context) {
return new CupertinoAlertDialog(
title: new Text("hello"),
content: new Text("hello"),
actions: <Widget>[
CupertinoDialogAction(
isDefaultAction: true,
child: Text("Ok"),
onPressed: () {
Navigator.pop(context);
}
),
CupertinoDialogAction(
child: Text("Cancel"),
onPressed: () {
Navigator.pop(context);
}
)
],
);
},
);
}

Keep in mind google_maps_flutter is a developer preview at version 0.0.3. Give it some time!
