Flutter Dart：无法加载 SVG 资产：无法加载资产 iconPath

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我体内时：

      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):   colorFilter: null)

请向我解释我错过了什么？

Answer 1

你有没有像下面的代码那样改变？

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,
          )
        )
      ),

只做 3 个工作：运行终端中的这个命令：flutter clean。

然后在 android 工作室转到文件并 select：缓存无效并重新启动。

然后通过这个命令再次获取依赖：flutter pub get
