BitmapDescriptor class abstract

Defines a bitmap image. For a marker, this class can be used to set the image of the marker icon. For a ground overlay, it can be used to set the image to place on the surface of the earth.

Use the BitmapDescriptor.asset or AssetMapBitmap.create to create a BitmapDescriptor image from an asset. Use the BitmapDescriptor.bytes or BytesMapBitmap to create a BitmapDescriptor image from a list of bytes. Use the BitmapDescriptor.defaultMarker to create a BitmapDescriptor for a default marker icon. Use the BitmapDescriptor.defaultMarkerWithHue to create a BitmapDescriptor for a default marker icon with a hue value.

Static Methods

asset(ImageConfiguration configuration, String assetName, {AssetBundle? bundle, String? package, double? width, double? height, double? imagePixelRatio, MapBitmapScaling bitmapScaling = MapBitmapScaling.auto}) → Future<AssetMapBitmap>

Creates a BitmapDescriptor from an asset using AssetMapBitmap.

bytes(Uint8List byteData, {double? imagePixelRatio, double? width, double? height, MapBitmapScaling bitmapScaling = MapBitmapScaling.auto}) → BytesMapBitmap

Creates a BitmapDescriptor from byte data using BytesMapBitmap.

defaultMarkerWithHue(double hue) → BitmapDescriptor

Creates a BitmapDescriptor that refers to a colorization of the default marker image. For convenience, there is a predefined set of hue values. See e.g. hueYellow.
