我想到的最简单的方法是下载 Whatsapp 的图标图像（从 flaticon 或其他网站），将其添加到项目的资产中并将其添加为子项（例如资产图像）。

Font Awesome has a flutter package that helps with most icons that are not in flutter default icon set, https://pub.dev/packages/font_awesome_flutter . It also includes all icons listed in font Awesome Offical website https://fontawesome.com/icons

 import 'package:font_awesome_flutter/font_awesome_flutter.dart';     

 Row(
                children: [
                  FloatingActionButton(
                    child: FaIcon(FontAwesomeIcons.whatsapp),
                      backgroundColor: Colors.green.shade800,
                    onPressed: () {
                      
                      String url =
                          "https://wa.me/+923045873730/?text=Hello";
                      launch(url);
                    
                    },
