大佬教程收集整理的这篇文章主要介绍了Flutter 测试结果为“在 null 上调用了 getter 'flavor'。”，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决Flutter 测试结果为“在 null 上调用了 getter 'flavor'。”？

开发过程中遇到Flutter 测试结果为“在 null 上调用了 getter 'flavor'。”的问题如何解决？下面主要结合日常开发的经验，给出你关于Flutter 测试结果为“在 null 上调用了 getter 'flavor'。”的解决方法建议，希望对你解决Flutter 测试结果为“在 null 上调用了 getter 'flavor'。”有所启发或帮助；

我正在为此应用进行质量保证测试，我想测试这个单独的页面。

但是我收到以下错误：

NoSuchMethodError：在 null 上调用了 getter 'flavor'。接收器：空尝试调用：味道

我使用的命令是：

Flutter run --flavor dev -t ./lib/pages/welcome_page/welcome_page.dart

我没有其他可以使用的口味。

风格信息是否应该从上一页传递到这个welcome_page.dart？
