Flutter：自定义字体

Question

解决方案发现：

使用Android Studio解决了该问题！！我使用Android Studio运行了该应用，一切正常！看起来VSCode不能很好地适应自定义字体。因此，当有人需要添加自定义字体时，我建议使用Android Studio。

我正在尝试在我的应用程序中使用一种称为“ Great Vibes”的Google字体。

这是我做的：

• 我在根文件夹中创建了一个“字体”目录
• 我将“ GreatVibes-Regular.ttf”文件复制到该目录中（从Google字体网站下载）
• 我在pubspec.yaml中对其进行了引用（请参见下文）
• [当我想使用它时，我在TextStyle中引用了它

结果：未使用字体。

fonts:
    - family: GreatVibes
      fonts:
        - asset: fonts/GreatVibes-Regular.ttf
          weight: 400


new Text('My New Font',
            style: new TextStyle(
              color: Colors.white,
              fontFamily: 'GreatVibes',
              fontSize: 16.0,
            )),
未报告错误。我还通过Online YAML parser验证了Yaml这是输出：
{
  "description": "My app", 
  "dependencies": {
    "http": "^0.11.3+16", 
    "shared_preferences": "^0.4.0", 
    "url_launcher": "^2.0.0", 
    "cupertino_icons": "^0.1.0", 
    "image_picker": "^0.4.1", 
    "flutter_facebook_login": "^1.0.3", 
    "flutter_localizations": {
      "sdk": "flutter"
    }, 
    "carousel_slider": "^0.0.4", 
    "connectivity": "^0.3.0", 
    "device_info": "^0.1.2", 
    "intl": "^0.15.5", 
    "font_awesome_flutter": "^7.0.0", 
    "scoped_model": "^0.2.0", 
    "flutter": {
      "sdk": "flutter"
    }, 
    "flutter_webview_plugin": "^0.1.4"
  }, 
  "flutter": {
    "fonts": [
      {
        "fonts": [
          {
            "asset": "fonts/GreatVibes-Regular.ttf", 
            "weight": 400
          }
        ], 
        "family": "GreatVibes"
      }
    ], 
    "assets": [
      "images/avatar.png", 
      "images/logo.png"
    ]
  }, 
  "name": "my_app", 
  "dev_dependencies": {
    "flutter_test": {
      "sdk": "flutter"
    }
  }
}
我也尝试过从设备中删除该应用程序并重新安装，但没有任何变化。
你有什么想法吗？

谢谢

如何在Flutter应用中使用自定义字体

Answer 2

发生该错误是因为pubspec.yaml不会自动保存，因此在运行获取包之前，请关闭pubspec.yaml文件并手动保存，再次运行获取包，现在应该可以解决问题。

Answer 3

Flutter的google_fonts软件包可让您轻松地在Flutter应用中使用fonts.google.com中的960种字体（及其变体）。
