【问题描述】：

我已经将我的颤振项目升级到 2.2 并且我升级了我的所有包。这是相机插件升级的问题。我尝试了很多方法，但都没有帮助。

我的错误之后

flutter 运行 --release

我遇到了同样的问题，我通过以下代码更改解决了它：

改变这个

android {
  compileSdkVersion 28

  defaultConfig {
     targetSdkVersion 28
  }
}

收件人

android {
  compileSdkVersion 30

  defaultConfig {
     targetSdkVersion 30
  }
}

抱歉没用 :((
还有问题吗？你能分享你的 Gradle 文件吗？
暂时我通过更改我的 contact_picker 包的 build.gradle 文件来修复它！ Here is explained
@RARGroup 在我的例子中，它使用该配置并且没有进行任何其他更改。
