مشکل در نصب پلاگین در فلاتر

سلام
من میخوام پلاگین های زیر رو نصب کنم ولی نمیدونم چرا ارور میدن

  http: ^0.12.0+2
  shared_preferences: ^0.5.3+1
  flutter_html_view: ^0.5.11

اینم اررو :

Running "flutter packages get" in alimelodi...                  
Because no versions of flutter_html_view match >0.5.11 <0.6.0 and flutter_html_view 0.5.11 depends on cached_network_image ^0.5.0+1, flutter_html_view ^0.5.11 requires cached_network_image ^0.5.0+1.
And because cached_network_image >=0.5.0+1 <0.6.0-alpha depends on flutter_cache_manager ^0.2.0+1, flutter_html_view ^0.5.11 requires flutter_cache_manager ^0.2.0+1.
Because flutter_cache_manager 0.2.0+1 depends on shared_preferences ^0.4.0 and no versions of flutter_cache_manager match >0.2.0+1 <0.3.0, flutter_cache_manager ^0.2.0+1 requires shared_preferences ^0.4.0.
Thus, flutter_html_view ^0.5.11 requires shared_preferences ^0.4.0.
So, because alimelodi depends on both flutter_html_view ^0.5.11 and shared_preferences ^0.5.3+1, version solving failed.
