Question

我是 Flutter 的新手，我尝试了 webview 和 flutter，它与 Android

配合得很好

我试图检查它是否有 iOS，但我得到了

我正在使用

webview_flutter: ^3.0.0

这是我的代码

import 'package:webview_flutter/webview_flutter.dart';

void main() => runApp(ScreenerWebView());

class ScreenerWebView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {

            preferredSize: Size.fromHeight(0),
            child: AppBar(
              // ignore: prefer_const_constructors
              title: SizedBox(
                height: kToolbarHeight,
              ),
            )),

Answer 1

webview_flutter 软件包不支持 macOS 目标，这就是您看到错误的原因

当你在 package 的 pubdev 上查看 Published x days ago 下的 flutter 徽章时，大多数时候它会告诉你支持哪些平台，如果是 webview_flutter 只有 android 和 ios

Flutter webview iOS 错误 "default webview implementation for targetPlatform.macOS but there isn't one"
