Usually this happens when your pubspec.yaml file, under dev-dependencies has uses-material-design set to false and its not including the material icons in your app.通常，当您的 pubspec.yaml 文件在 dev-dependencies 下将uses-material-design设置为 false 并且它不包括应用程序中的材质图标时，就会发生这种情况。
Change it to true, and restart the app.将其更改为 true，然后重新启动应用程序。 It should work after that.它应该在那之后工作。

I found the issue, the material icon codes where replaced in this SDK and I was using IconData instead of referencing by their name.我发现了这个问题，在这个 SDK 中替换了材质图标代码，我使用的是 IconData 而不是通过它们的名称引用。 So I updated the code to be like:所以我将代码更新为：
Icon(Icons.arrow_back_ios_new_rounded, size: 20)
