颤振飞镖：无法加载 SVG 资源：无法加载资产图标路径

Question

我正在尝试使用flutter_svg包加载一些。svg图标。

class _MyHomePageState extends State<MyHomePage> {
final String iconPath = "assets/icons/adept.svg";
...
}

我将包含icons/文件夹的assets/文件夹添加到pubspec.yaml文件:

assets:
- assets/

当我尝试将图标加载到body中时:

body: Center(
child: Container(
child: LimitedBox(
child: SvgPicture.asset('iconPath', color: Colors.black, width: 100, height: 100,),
maxHeight: 100,
maxWidth: 100,
)
)
),

我得到这个StackTrace，无法加载资产:assetName，

I/flutter (10154): ══╡ EXCEPTION CAUGHT BY SVG ╞═══════════════════════════════════════════════════════════════════════
I/flutter (10154): The following assertion was thrown resolving a single-frame picture stream:

I/flutter (10154):   colorFilter: null)
I/flutter (10154): ════════════════════════════════════════════════════════════════════════════════════════════════════

请告诉我我错过了什么?

Answer 1

您是否更改了下面的代码?

assets:
- assets/
- assets/icons/

body: Center(
child: Container(
child: LimitedBox(
child: SvgPicture.asset(iconPath, color: Colors.black, width: 100, height: 100,),
maxHeight: 100,
maxWidth: 100,
)
)
),

Answer 2

刚刚做了3件事:在终端运行这个命令:flutter clean.

，在android studio中进入file并选择:无效缓存，重新启动。

然后通过此命令再次获取依赖项:flutter pub get
