将android studio升级到3.2.1和flutter插件后,我无法运行我的应用,出现以下错误:
Error: unable to locate asset entry in pubspec.yaml: "assets/CupertinoIcons.ttf".

这是我的pubspec.yaml,我在其他机器上对该工程进行了测试,并且我认为代码没有问题。

在cupertino_icons
文件中查找.packages
并删除文件夹(没有lib
)
如果有
cupertino_icons:file:///Users/myuser/.pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.2/lib/
然后删除
cupertino_icons:file:///Users/myuser/.pub-cache/hosted/pub.dartlang.org/cupertino_icons-0.1.2/
然后再次运行flutter packages get
。

我对此有解决方案。请尝试以下代码。
如果我们在FontManifest.json文件中添加字体,则字体将应用于您的代码中。
这是一个代码,
FontManifest.json
[
{
"fonts": [
{
"asset": "fonts/MaterialIcons-Regular.ttf"
}
],
"family": "MaterialIcons"
},
{
"fonts": [
{
"asset": "fonts/MontserratSemiBold.ttf"
}
],
"family": "MontserratSemiBold"
}
]
以上代码解决了我的2个Flutter网络问题,
(1)字体渲染和
(2)图标渲染
希望它也会为您提供帮助。 :)

确保您的路径正确,否则可能会错过- / lib 。 最终路径如下所示:lib / assets / CupertinoIcons.ttf
