我正在尝试安装Flutter软件包“image_picker”。当我运行flutter pub add image_picker时，我得到以下错误：

The current Dart SDK version is 3.0.1.

Because image_picker <0.7.0-nullsafety doesn't support null safety and image_picker >=0.8.4 <0.8.6 depends   
  on image_picker_platform_interface ^2.3.0, image_picker <0.7.0-nullsafety or >=0.8.4 <0.8.6-∞ requires     
  image_picker_platform_interface ^2.3.0.
And because image_picker >=0.8.2 <0.8.4 depends on image_picker_platform_interface ^2.2.0, image_picker
  <0.7.0-nullsafety or >=0.8.2 <0.8.6-∞ requires image_picker_platform_interface ^2.2.0.
And because image_picker >=0.8.1 <0.8.2 depends on image_picker_platform_interface ^2.1.0 and image_picker
  >=0.7.0 <0.8.1 depends on image_picker_platform_interface ^2.0.0, image_picker <0.7.0-nullsafety or >=0.7.0  <0.8.6-∞ requires image_picker_platform_interface ^2.0.0.
Because image_picker_platform_interface >=2.0.0-nullsafety <2.0.0 depends on http ^0.13.0-nullsafety.0 and   
  image_picker >=0.7.0-nullsafety <0.7.0 depends on image_picker_platform_interface ^2.0.0-nullsafety,
  image_picker >=0.7.0-nullsafety <0.7.0 requires http ^0.13.0-nullsafety.0 or
  image_picker_platform_interface ^2.0.0.
Thus, image_picker <0.8.6 requires http ^0.13.0-nullsafety.0 or image_picker_platform_interface ^2.0.0.      
And because image_picker >=0.8.6 depends on image_picker_platform_interface ^2.6.1, every version of
  image_picker requires http ^0.13.0-nullsafety.0 or image_picker_platform_interface ^2.0.0.
And because image_picker_platform_interface >=2.0.0 depends on http ^0.13.0 and google_fonts >=4.0.5
  depends on http ^1.0.0, google_fonts >=4.0.5 is incompatible with image_picker.
So, because favorite_places_app depends on both google_fonts ^4.0.5 and image_picker any, version solving    
  failed.

The lower bound of "sdk: '>=1.8.0 <2.0.0 or >=2.0.0-dev.28.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.

我还尝试通过在pubspec.yaml中的dependencies下插入名称来安装软件包，但结果相同。
