Android 错误：无法在pubspec.yaml中找到资产条目；assets/fonts/Lato Regular.ttf“；

在我写这篇文章之前，我到处寻找我的错误，但什么也没找到

虽然我在pubspec.yaml文件中正确地记录了所有内容，但在调试控制台中出现以下错误：

Launching lib/main.dart on Android SDK built for x86 in debug mode...
Error: unable to locate asset entry in pubspec.yaml: "assets/fonts/Lato-Regular.ttf".
✓ Built build/app/outputs/apk/debug/app-debug.apk.
Error: unable to locate asset entry in pubspec.yaml: "assets/fonts/Lato-Regular.ttf".
Exited (sigterm)

我的pubspec.yaml文件如下所示：

lib/assets/fonts/Lato-Regular.ttf

旁注：为了避免手动导入字体，我推荐这个软件包。它有数百种字体，包括Lato，您可以使用
GoogleFonts.Lato（）访问它
要获得Lato字体的默认
TextStyle
，而不必通过
pubspec.yml
文件导入它。
我也犯了与您相同的错误，请正确指定文件夹的位置，如果在lib文件夹内，则必须将路径写入：

lib/assets/fonts/Lato-Regular.ttf

如问题中所述

有些用户不喜欢这种方式，他们宁愿在lib之外创建文件夹

希望它能回答您的问题。
如果您的字体没有字体系列，请尝试使用以下字体：

创建资产文件夹
将字体文件移动到“资源”文件夹下
给你的字体文件起一个简单的名字。比如没有大写的特殊字符
在pubspec.yaml中添加此代码
跑酒吧


停止应用程序并重新启动它


只需在更多时间检查缩进，如制表符、空格等
我建议从中复制代码，然后对其进行更改。
还有一件事，如果您的字体位于lib/assets/fonts文件夹中，您应该在yaml文件中提到根目录的总路径。
愉快的调试：）
我认为我们的问题和代码与我在教程中遵循的相同。我的替代方法是在lighter项目中使用google fonts online。尝试访问此网站，您将获得有关如何使用自定义字体的信息。
缩进对我有效。。。
