Answer 1

在花了三个多小时之后，我终于解决了。

对于那些升级到1.20.1或更高版本的用户，请确保在pubspec.yaml中添加这一行。

dependency_overrides:
  analyzer: '0.39.14'

Answer 2

我也有过同样的问题：

请在您的公共文件中试试这个。

dependency_overrides:
  analyzer: '0.39.17'    
  build_resolvers: '1.3.10'

Answer 3

试一试：

1- flutter clean

2-进入开发频道：flutter channel dev

3-升级：flutter upgrade --force

4- flutter pub get

5.试着建造

6-返回稳定或主信道：flutter channel stable (flutter channel master)

7-升级：flutter upgrade --force
