Fields

PolygonsProperty

Identifies the Polygons bindable property.

Declaration

public static readonly BindableProperty PolygonsProperty

Field Value

Type
Microsoft.Maui.Controls.BindableProperty

Properties

Polygons

Gets or sets the collection of polygon. Every single MapPolygon is a closed path which connects multiple location coordinates through group of Points.

Declaration

public ObservableCollection<MapPolygon> Polygons { get; set; }

Property Value
