flutter - 无法在我的颤振项目中安装依赖项

Question

我正在尝试在我的颤振项目中安装 image_picker 和 firbase_storage。但无论我尝试安装什么版本，它都失败了。并给出这样的错误 -

Because image_picker >=0.3.0 requires Flutter SDK version >=0.1.4 <2.0.0 and image_picker <0.3.0 requires SDK version >=1.8.0 <2.0.0, image_picker is forbidden.

我已经尝试安装每个版本，但甚至无法安装单个版本。

Flutter doctor -v 工作正常，以下是我的 pubspec.yaml 文件的内容

name: timepass
description: A new Flutter project.

    sdk: ">=2.0.0-dev.68.0 <3.0.0"

您需要允许更新的image_picker版本。

尝试

dependencies:
  image_picker:

或者

dependencies:
  image_picker: ^0.5.0
