我创建了一个 flutter web 项目，它使用网络图像和 Assets 图像，在我的电脑上调试时一切正常，但是当我将它部署到网络服务器时，网络图像工作正常，但 Assets 图像根本不显示。当我在 Web 浏览器控制台中检查页面时，出现以下错误:
$1 @ window.dart:120
/assets/slack.png:1 Failed to load resource: the server responded with a status of 503 ()
window.dart:120 Error while trying to load an asset: Failed to load asset at "assets/slack.png" (503)

最佳答案
您应该将照片添加到 pubspec.yaml 文件并将您的 Assets 文件夹上传到 Web 服务器。可能是关于不上传文件夹
