Static Methods

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.
fromAssetImage(ImageConfiguration configuration, String assetName, {AssetBundle? bundle, String? package, bool mipmaps = true}) → Future<BitmapDescriptor>
Creates a BitmapDescriptor from an asset image.
fromBytes(Uint8List byteData, {Size? size}) → BitmapDescriptor
Creates a BitmapDescriptor using an array of bytes that must be encoded as PNG. On the web, the size parameter represents the physical size of the bitmap, regardless of the actual resolution of the encoded PNG. This helps the browser to render High-DPI images at the correct size. size is not required (and ignored, if passed) in other platforms.
