Flutter项目无法安装最新版image_picker插件问题求助

问题情况 #

• 执行命令$ flutter pub add image_picker安装插件，当前插件最新版本为1.0.1，但项目的pubspec.yaml文件中显示的版本却是0.7.2+1
• image_picker从0.8.2版本开始新增了不少方法（例如ImagePicker().getImage(...)已替换为ImagePicker().pickImage(...)），目前无法使用这些新方法

手动升级后的错误 #

手动将pubspec.yaml里的image_picker版本改为1.0.1后，执行$ flutter pub get命令时触发如下错误：

Because image_picker >=1.0.1 depends on image_picker_for_web ^2.2.0 which depends on flutter_web_plugins from sdk, image_picker >=1.0.1 requires flutter_web_plugins from sdk.
So, because flutter_web_plugins from sdk doesn't exist (could not find package flutter_web_plugins in the Flutter SDK) and my_app depends on image_picker ^1.0.1, version solving failed.
exit code 69
