如何检测Flutter应用程序是否正在网络上运行？ [英] How can I detect if my Flutter app is running in the web?

问题描述

我知道我可以使用 Platform.isAndroid ， Platform.isIOS 等检测操作系统，但是没有类似 Platform.isWeb 的东西，那么我该如何检测呢？

I know that I can detect the operating system with Platform.isAndroid, Platform.isIOS, etc. but there isn't something like Platform.isWeb so how can I detect this?

推荐答案

有一个全局布尔 kIsWeb ，它可以告诉您该应用是否已编译为可以在网络上运行。

There is a global boolean kIsWeb which can tell you whether or not the app was compiled to run on the web.

文档： https://api.flutter.dev/flutter/ foundation / kIsWeb-constant.html

import 'package:flutter/foundation.dart' show kIsWeb;

if (kIsWeb) {
  // running on the web!
} else {
  // NOT running on the web! You can check for additional platforms here.
}
