エラー:pubspec.yamlでアセットエントリが見つかりません: "assets / fonts / Lato-Regular.ttf"

これを書く前に、どこでも間違いを探しましたが、何も見つかりませんでした。

すべてが正しく、pubspec.yamlファイルに書き留められていますが、デバッグコンソールで次のエラーが発生します。

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".

私のpubspec.yamlファイルは次のようになります。

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

  # Use with the CupertinoIcons class for iOS style icons.

# 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

多分私を助けてくれますか?解決策が見つからない

アセットフォルダはルートパス(/)にある必要があります。 libフォルダーに保持する場合は、次のようにlibをアセットの前に置きます。

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

補足:フォントを手動でインポートする必要がないように、 google_fonts パッケージをお勧めします。 Latoを含む何百ものフォントがあり、GoogleFonts.lato()でアクセスして、_pubspec.yml_ファイル経由でインポートすることなく、LatoフォントでデフォルトのTextStyleを取得できます。
