How to remove outline of marker/change marker style when using plot.scatter in pandas
Date : March 29 2020, 07:55 AM
hope this fix your issue As docs for pandas.DataFrame.scatter say, we can pass optional keyword arguments to pandas.DataFrame.plot which in turn will pass some of them to a corresponding matplotlib plotting method, matplotlib.axes.Axes.scatter in your case. So, for example, to eliminate the edges from the markers, and to change them to hexagons, you can write: df.plot.scatter(x='Supply',
y='Demand',
alpha=0.2,
figsize=(6,6),
s=100,
linewidths=0.0,
marker='h')

Problem with google_maps_flutter, marker onTap(){} doesn't work
Date : March 29 2020, 07:55 AM
like below fixes the issue Save a reference of your BuildContext which is provided by the build method in a variable and pass that context variable to the Navigator. class MapScreen extends StatefulWidget{
...
}
class MapScreenState extends State<MapScreen>{
BuildContext _myContext;
@override
Widget build(BuildContext context) {
_myContext = context;
Marker servicioej= Marker(
markerId: MarkerId('marker1'),
position: LatLng(-32.3162695, -58.0949139),
infoWindow: InfoWindow(
title: 'Restaurante',
onTap: () {
Navigator.push(_myContext, MaterialPageRoute(builder: (context) => ServicioStateful()));
}),
icon: BitmapDescriptor.defaultMarkerWithHue(BitmapDescriptor.hueBlue),
);
return Scaffold(
...
);
}
}

Flutter - How to remove an individual google_maps_flutter ^0.5.21 marker?
Tag : ios , By : Andrew L.

Hope this helps I assume somewhere in your build() function you have the Google Maps widget: GoogleMap(
markers: _markers,
...
_markers.remove(_markers.firstWhere((Marker marker) => marker.markerId.value == title));
_markers.remove(_markers.firstWhere((Marker marker) => marker.markerId == MarkerId(title)));

this will help I found out that it can be made by styling the map and removing unwanted parts away. You can also make some sick looking design too. Very useful.

How to create text inside marker with google_maps_flutter?
Tag : flutter , By : Gerhard Miller
Date : October 01 2020, 03:00 AM
This might help you This is a demo image of what I need. , I managed to solve with this method Future<BitmapDescriptor> createCustomMarkerBitmap(String title) async {
TextSpan span = new TextSpan(
style: new TextStyle(
color: Prefs.singleton().getTheme() == 'Dark'
? Colors.white
: Colors.black,
fontSize: 35.0,
fontWeight: FontWeight.bold,
),
text: title,
);
TextPainter tp = new TextPainter(
text: span,
textAlign: TextAlign.center,
textDirection: TextDirection.ltr,
);
PictureRecorder recorder = new PictureRecorder();
Canvas c = new Canvas(recorder);
tp.layout();
tp.paint(c, new Offset(20.0, 10.0));
/* Do your painting of the custom icon here, including drawing text, shapes, etc. */
Picture p = recorder.endRecording();
ByteData pngBytes =
await (await p.toImage(tp.width.toInt() + 40, tp.height.toInt() + 20))
.toByteData(format: ImageByteFormat.png);
Uint8List data = Uint8List.view(pngBytes.buffer);
return BitmapDescriptor.fromBytes(data);
}
BitmapDescriptor bitmapDescriptor = await createCustomMarkerBitmap(...);
Marker marker = Marker(
/* in addition to your other properties: */
icon: bitmapDescriptor
);
