AMap.TileLayer.Flexible

Flexible tile layer, inherited from AMap.TileLayer, developers can specify the content of each tile by passing the createTile field during construction. Construct a Flexible layer object and set the layer properties through FlexibleLayerOptions

new AMap.TileLayer.Flexible(opts: FlexibleLayerOptions)
