不能同时为容器提供颜色和装饰

Question

每次我重新启动代码以检查应用程序时，都会出现一个错误，提示 无法同时提供颜色和装饰，颜色参数只是“装饰：新 Boxdecoration”的缩写（颜色：颜色）“ 也许它是真的，我有一个错误，但它没有说明它在哪里？当我删除诸如字体大小、小部件或与错误无关的内容并重新加载应用程序时，应用程序启动时没有任何问题或错误显示...

Answer 1

您不能同时为 Container() 提供颜色和装饰。如果您希望为 Container 提供颜色和装饰，请在 Boxdecoration() 中提供颜色。下面的代码将起作用。

Container(
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(10),
)),

Answer 2

尝试在 decoration 中添加 color，如下所示：

Container(
  decoration: BoxDecoration(
    color: Colors.red
  ),
  child: //add you desired code here
),

这一定能帮到你
