耀斑动画不会显示在屏幕上。我在用着：

Container(
              height: 300.0,
              width: 300.0,
              child: FlareActor('checkmarkone.flr',
                  fit: BoxFit.contain,
                  alignment: Alignment.center,
              ),
            ),

当我运行应用程序时，我在运行控制台中收到此消息：

[VERBOSE-2:ui_dart_state.cc(157)] Unhandled Exception: Unable to load asset: checkmarkone.flr
#0      PlatformAssetBundle.load (package:flutter/src/services/asset_bundle.dart:221:7)

#10     RenderObjectWithChildMixin.child= (package:flutter/src/rendering/object.dart:2905:7)<…&gt;

我感谢所有建议。谢谢

确保您checkmarkone.flr的资产文件夹中有文件，然后将其添加到您的 pubspec.yaml 文件中

flutter:
  assets:
    - checkmarkone.flr

然后，运行flutter packages get命令来更新依赖项。最后，冷重启你的项目

请检查您的pubspec.yaml文件并确保该文件checkmarkone.flr已正确添加/加载。

例如。

发布规范.yaml

... (more on top)
# 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:
   - assets/checkmarkone.flr # Add it here
... (more on bottom)

现在等待颤振任务（更新包）完成，然后尝试使用上面添加的资产路径通过热重启在屏幕/小部件中加载 Flare 动画。

小部件.dart


Container(
  height: 300.0,
  width: 300.0,
  child: FlareActor('assets/checkmarkone.flr',
      fit: BoxFit.contain,
      alignment: Alignment.center,
  ),
),
