Question

在我写这篇文章之前，我到处搜索了我的错误，但是没有发现任何东西。

尽管我一切正确，并记在pubspec.yaml文件中，但在调试控制台中却收到此错误：

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：

name: shopping_app
description: A new Flutter project.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: Lato
      fonts:
        - asset: assets/fonts/Lato-Regular.ttf
        - asset: assets/fonts/Lato-Bold.ttf
          weight: 700
    - family: Anton
      fonts:
        - asset: assets/fonts/Anton-Regular.ttf
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.dev/custom-fonts/#from-packages

这是字体在其中的路径：

也许可以帮我吗？我只是找不到解决方法

最好的问候

Answer 1

如果您的字体没有字体家族，请尝试使用此字体：

创建资产文件夹
将字体文件移动到资产文件夹下。
给字体文件起一个简单的名字。就像没有大写的特殊字符一样。
将此代码添加到pubspec.yaml

fonts:
    - family: CustomFamilyName
      fonts:
        - asset: assets/fontfile.ttf

运行pub get
停止应用并重新启动。

Answer 2

资产文件夹应位于根路径（/）中。如果要将其保留在lib文件夹中，请将lib放在资产前面，如下所示：

//new path
lib/assets/fonts/Lato-Regular.ttf

旁注：为避免必须手动导入字体，我建议使用google_fonts软件包。它具有包括Lato在内的数百种字体，您可以使用GoogleFonts.lato()访问它以获得Lato字体的默认TextStyle，而不必通过pubspec.yml文件导入。

Answer 3

我也犯了与您相同的错误，请正确指定文件夹的位置，如果位于lib文件夹中，则必须将路径写为：

lib/assets/fonts/Lato-Regular.ttf

如问题所述。

一些用户不喜欢这种方式，他们宁愿在lib之外创建文件夹。

希望它回答了您的问题。

Answer 4

只需检查更多时间的缩进，例如制表符和空格以及所有我建议从flutter-font-declaration复制代码，然后对其进行更改。还有一件事是，如果字体在lib / assets / fonts文件夹中，则应在yaml文件中提及根目录的总路径。调试愉快：）

Answer 5

我认为我们有我在 udemy 教程中遵循的相同问题和确切代码。我的替代方法是在线使用谷歌字体进行更轻的项目。尝试访问此站点，您将获得有关如何使用自定义字体的信息。 https://pub.dev/packages/google_fonts

Answer 6

我遇到了同样的问题。我的问题是我首先在 Windows 上编写了我的 flutter 应用程序代码，所以在 pubspec.yaml 中我使用反斜杠写了字体文件夹的路径，现在我试图在 linux 系统上运行我的代码，该系统使用正斜杠代替反斜杠作为路径（ mac OSX 也是如此）

所以检查你是否有同样的问题？

错误：无法在pubspec.yaml中找到资产条目：“资产/字体/Lato-Regular.ttf”
