我想在屏幕上显示的Google地图上添加网络图像作为标记。该API支持功能Bitmapdescriptor.fromBytes()
。但是,我不知道如何将其与网络映像一起使用。
BitmapDescriptor.fromBytes(byteData);
答案 0 :(得分:2)
首先导入此内容:-
import 'package:http/http.dart' as http;
主要代码:-
var iconurl ="your url";
var dataBytes;
var request = await http.get(iconurl);
var bytes = await request.bodyBytes;
setState(() {
dataBytes = bytes;
});
LatLng _lastMapPositionPoints = LatLng(
double.parse("22.7339"),
double.parse("75.8499"));
_markers.add(Marker(
icon: BitmapDescriptor.fromBytes(dataBytes.buffer.asUint8List()),
markerId: MarkerId(_lastMapPositionPoints.toString()),
position: _lastMapPositionPoints,
infoWindow: InfoWindow(
title: "Delivery Point",
snippet:
"My Position",
),
));
