在vs代码上运行flutter应用程序时,出现此错误: lib / ui / pages / home_pages / ads_view.dart:65:39:错误:没有名为“列表”的命名参数。

from django.forms import forms
    
#then I change as below field:
    
from django import forms

这是代码:

                                      ^^^^
../../../Desktop/flutter/packages/flutter/lib/src/painting/gradient.dart:366:9: Context: Found this candidate, but the arguments don't match.
  const LinearGradient({
        ^^^^^^^^^^^^^^

使用colors属性代替List

Container(
  decoration: BoxDecoration(
    gradient: LinearGradient(
      colors: [Colors.black87, Colors.transparent], // Here it is
      begin: Alignment.bottomCenter,
      end: Alignment.center,
    ),
  ),
)
