如何在 Flutter Web 中渲染 SVG？

Question

我的最终目标是将 Flutter 移动应用程序转换为 Flutter Web 应用程序。我在 Flutter 移动应用程序中使用了flutter_svg但在 Flutter Web 应用程序中不起作用。

Flutter web 的替代插件是什么？

当我使用 chrome 在 chrome 中运行项目时出现错误flutter run -d chrome。

The following UnimplementedError was thrown during paint():
UnimplementedError

The relevant error-causing widget was:
  RawPicture
  file:///C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_svg-0.17.4/lib/svg.dart:729:22

When the exception was thrown, this was the stack:
C:/b/s/w/ir/cache/builder/src/out/host_debug/dart-sdk/lib/_internal/js_dev_runtime/private/ddc_runtime/errors.dart 214:49  throw_

packages/flutter/src/rendering/object.dart 184:12                                                                          paintChild
packages/flutter/src/rendering/proxy_box.dart 131:14                                                                       paint

或者如何在 Flutter Web 的 flutter_svg 插件中解决这个问题？

Answer 1

现在你可以使用Image.networkweb 来渲染这样的 svg

child: kIsWeb 
    ? Image.network("/assets/$assetName",
    width: width,
    height: height,
    fit: fit,
    color: color,
    alignment: alignment,
    semanticLabel: semanticsLabel)
    : SvgPicture.asset(assetName,
    width: width,
    height: height,
    fit: fit,
    color: color,
    alignment: alignment,
    semanticsLabel: semanticsLabel)
