我可以通过传递标志在我的手机上以发布模式运行应用程序--no-sound-null-safety --release，但既不能flutter build apk --enable-experiment=non-nullable 也flutter build apk --no-sound-null-safety 不能flutter build apk --enable-experiment=non-nullable --no-sound-null-safety 工作

我想在我的一些包含SvgPicture小部件的屏幕上进行小部件测试，但我不能这样做，因为它会引发异常。

重现错误的代码：

import \'package:flutter/material.dart\';\nimport \'package:flutter_svg/svg.dart\';\nimport \'package:flutter_test/flutter_test.dart\';\n\n\nvoid main() {\n  testWidgets(\n    \'SvgPicture.asset passes\',\n    (WidgetTester tester) async {\n      await tester.pumpWidget(MaterialApp(\n        home: Scaffold(\n          body: SvgPicture.asset(\'icons/pencil.svg\'),\n        ),\n      ));\n      await tester.pump();\n    },\n  );\n}\n

执行结果：
