flutter版本：2.0.4
provider版本：3.2.0

问题原因

provider该版本中使用了flutter2.x.x不兼容的方法，讲provider升级到新版（如provider 5.0.0）即可。

解决办法

编辑项目根目录下的【pubspec.yaml】文件，把【dependencies】下的【provider】版本改为5.0.0，以我的为例：

dependencies:flutter:sdk: flutter# The following adds the Cupertino Icons font to your application.# Use with the CupertinoIcons class for iOS style icons.cupertino_icons: ^0.1.2provider: ^5.0.0

结束！
