Run Sample App

[bruceo-beflex]

class MapWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new FlutterMap(
      layers: [
        TileLayerOptions(
            urlTemplate: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
            subdomains: ['a', 'b', 'c']),
      ],
      options: MapOptions(
        center: LatLng(51, 32),
        zoom: 5.0,
      ),
    );
  }
}

with sample code, i keep getting an error

flutter: ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════

CustomPoint getNewPixelOrigin(LatLng center, [double zoom]) {

CustomPoint round() {
var x = this.x is double ? this.x.round() : this.x;
var y = this.y is double ? this.y.round() : this.y;
return CustomPoint(x, y);
}

when it runs round(), it causes an exception error and it say x is infinity on debug point.

Am I doing something wrong?

Hi, @bruceGwanhoOh. I'm getting the same issue. Since you closed this, does this mean you found a way to fix it? Like you, I'm just using the sample code.

Ah, I think I'm starting to get this. When I look at this, my MapState.size is being set to CustomPoint (411.42857142857144, Infinity). That appears to be a legitimate value, as box.dart:164 explicitly says infinity is an allowed value. So am I supposed to wrap this in another widget? Right now I just have it in a column.
