flutter - 使用 image_picker 时构建失败并出现异常

Question

当我将 image_picker 添加到我的 pubspec.yaml 时，我无法运行我的应用程序。

当我删除 image_picker 依赖项时，应用程序构建没有错误。我什至没有编写代码来使用依赖项，应用程序将无法构建。我的 pubspec.yaml 有以下依赖项:

dependencies:
  flutter:
    sdk: flutter
  image_picker:
  http:
  google_maps_flutter: ^0.0.3+3
  geolocator:

当我尝试构建应用程序时，调试控制台中出现错误。

该插件已从已弃用的 Android 支持库更新到 AndroidX。使用 AndroidX 迁移应用程序。或者，使用固定到主要版本 0.4.12 的此插件。

dependencies:
  flutter:
    sdk: flutter
  image_picker: ^0.4.12
